Abstract:

During the last few years, synthetic self-healing materials have become a new class of emerging smart materials with the ability to repair damage and restore lost or degraded properties or performance using resources inherently available to the system. Success in the design of self-healing materials is important to material safety, product reliability and prolonged lifetime. This article covers fundamental material-independent principles and different self-healing approaches for polymeric materials. Among these approaches, some depend on specific external stimulus to achieve their goal while others regain the physical properties of the pristine material without such external intervention. Both the mechanisms and performance of different methods are discussed and evaluated, along with their advantages and disadvantages. In the end, both the potential application areas and the main challenges are also discussed in this article for a better understanding of future development trend of self-healing polymeric materials.

Abstract:

Polymerization reactions are generally divided into two broad classes: step growth or polycondensation reactions (examples would include the synthesis of polyamides and polyesters), and chain growth processes such as those used to prepare polyethylene or polystyrene. These processes are illustrated schematically in Figure 1.The statistical nature of step and chain growth polymerization processes ensures that the products of such reactions must be heterogeneous. Conventional polymeric materials thus consist of mixtures of chains, often characterized by relatively broad distributions of chain length or composition. In many materials applications, this kind of molecular heterogeneity is advantageous since it suppresses crystallization and helps to preserve desirable properties such as optical clarity or elasticity. On the other hand, synthetic developments that afford improved control of macromolecular architecture have had profound impact on materials science and technology. As examples, one can cite the discovery of Ziegler-Natta polymerization, now used to prepare billions of pounds per year of crystalline polyolefins, or the development of living anionic polymerization of olefins, which led directly to block copolymers and the commercially important thermoplastic elastomers.The advent of recombinant DNA methods has provided a basis for developing polymeric materials characterized by essentially absolute uniformity of chain length, sequence, and stereochemistry. This article outlines the principles governing the cloning and expression of artificial genes, and examines the potential role of artificial proteins in polymer materials science.

Abstract:

Rare earth elements (REEs) play indispensable roles in various advanced technologies, from electronics to renewable energy. However, the heavy global REEs supply and the environmental impact of traditional mining practices have spurred the search for sustainable REEs recovery methods. Polymeric materials have emerged as promising candidates due to their selective adsorption capabilities, versatility, scalability, and regenerability. This paper provides an extensive overview of polymeric materials for REEs recovery, including polymeric resins, polymer membranes, cross-linked polymer networks, and nanocomposite polymers. Each category is examined for its advantages, challenges, and notable developments. Furthermore, we highlight the potential of polymeric materials to contribute to eco-friendly and efficient REEs recovery, while acknowledging the need to address challenges such as selectivity, stability, and scalability. The research in this field actively seeks innovative solutions to reduce reliance on hazardous chemicals and minimize waste generation. As the demand for REEs continues to rise, the development of sustainable REEs recovery technologies remains a critical area of investigation, with the collaboration between researchers and industry experts driving progress in this evolving field.

Abstract:

This paper presents data on the development of polymer composite materials based on thermoplastic elastomers. As starting materials for the synthesis of the matrix components were selected as follows: isotactic polypropylene and ternary ethylene-propylene-diene elastomer (EPDM). Diene component in EPDM are ethylidene norbornene composition in an amount of 4-5%. Dynamic vulcanization was carried out using the elastomer element sulfur. The filler polymer composite materials used silica gel with dimethyl polysiloxane. Synthesis was carried out by filling the sol-gel technology. The filler content in the composite varied from 10 to 80% by weight. Mixing of filler and the matrix was performed in a laboratory twin-rotor mixer, type &#34;Brabender&#34;. It is found that the maximum possible filler content of the matrix used was 80%. With the introduction of more filler mixing of the components it has been difficult. When the filler content from 10 to 70% of parameters such as tensile strength, flexural strength and modulus of longitudinal elasticity increasing and administered at higher filler and 80 wt%. markedly reduced. Thus, it can be concluded that the content of filler in the composite is 70%. Further research should be directed to the evaluation of the radiation resistance of the developed composite materials.

Abstract:

The analysis of the phenomena occurring during the interaction of polymeric materials with aggressive media is carried out. Scientifically substantiated is the chemical effect on workpieces made from polymeric materials before cutting. In this case, it is advisable to carry out the processing of polymers with an aggressive medium in such a way as to ensure cracking or loosening of the surface layer to a certain depth, without changing the chemical properties of a particular polymer. The results of experimental studies of samples in tension after appropriate chemical treatment are carried out. The research results analysis made it possible to establish the fact that the treatment of the studied polymeric materials with active media leads to a significant decrease in strength. Methods have been developed, the essence of which is a directed change in the properties of the processed material, by preliminary chemical treatment of the surface layer, in order to reduce the resistance to destruction of the surface layer of the workpiece during its subsequent interaction with the cutting tool.

The composite design is combined with processing tools and advanced characterization techniques that result in laminates with reliability, traceability and quality. The platform begins with the identification of energy dissipation mechanisms and the detailed characterization of the polymeric resin. It includes the Time – Temperature – Transformation Diagram (TTT- Diagram) that supplies the optimal processing conditions.

Abstract:

The development of a novel artificial heart valve with outstanding durability and safety has remained a challenge since the first mechanical heart valve entered the market 65 years ago. Recent progress in high-molecular compounds opened new horizons in overcoming major drawbacks of mechanical and tissue heart valves (dysfunction and failure, tissue degradation, calcification, high immunogenic potential, and high risk of thrombosis), providing new insights into the development of an ideal artificial heart valve. Polymeric heart valves can best mimic the tissue-level mechanical behavior of the native valves. This review summarizes the evolution of polymeric heart valves and the state-of-the-art approaches to their development, fabrication, and manufacturing. The review discusses the biocompatibility and durability testing of previously investigated polymeric materials and presents the most recent developments, including the first human clinical trials of LifePolymer. New promising functional polymers, nanocomposite biomaterials, and valve designs are discussed in terms of their potential application in the development of an ideal polymeric heart valve. The superiority and inferiority of nanocomposite and hybrid materials to non-modified polymers are reported. The review proposes several concepts potentially suitable to address the above-mentioned challenges arising in the R&D of polymeric heart valves from the properties, structure, and surface of polymeric materials. Additive manufacturing, nanotechnology, anisotropy control, machine learning, and advanced modeling tools have given the green light to set new directions for polymeric heart valves.

Abstract:

There has been increasing interest in the study and development of nanoparticle-embedded polymeric materials and their applications to special membranes. Nanoparticle-embedded polymeric materials have been observed to have a desirable compatibility with commonly used membrane matrices, a wide range of functionalities, and tunable physicochemical properties. The development of nanoparticle-embedded polymeric materials has shown great potential to overcome the longstanding challenges faced by the membrane separation industry. One major challenge that has been a bottleneck to the progress and use of membranes is the balance between the selectivity and the permeability of the membranes. Recent developments in the fabrication of nanoparticle-embedded polymeric materials have focused on how to further tune the properties of the nanoparticles and membranes to improve the performance of the membranes even further. Techniques for improving the performance of nanoparticle-embedded membranes by exploiting their surface characteristics and internal pore and channel structures to a significant degree have been incorporated into the fabrication processes. Several fabrication techniques are discussed in this paper and used to produce both mixed-matrix membranes and homogenous nanoparticle-embedded polymeric materials. The discussed fabrication techniques include interfacial polymerization, self-assembly, surface coating, and phase inversion. With the current interest shown in the field of nanoparticle-embedded polymeric materials, it is expected that better-performing membranes will be developed soon.

Abstract:

Abstract As the semiconductor technology and the field evolves, the need for new applications can facilitate the development of new materials and processes. Device size is continuously shrinking, and materials that have low stress can promote new developments. In this paper, the focus is on three polymeric platforms that can be used as dielectric materials with the added advantage of being patternable via laser ablation. The dielectric materials were carefully designed to exhibit low stress (low modulus and high elongation), good temperature stability, and high absorbance for laser patterning. Additionally, these materials possess a distinctly advantageous, heretofore unseen property: production of little to no debris post-ablation. Several advantages of using laser ablation as the patterning tool is that it allows room temperature processing, higher throughput, and improved resolution. In this paper, it will be demonstrated that successful patterning via laser ablation of new dielectric materials can be achieved which is beneficial to new applications and technologies.

Abstract:

The design and development of polymeric materials have been a hot domain for decades. However, traditional experiments and molecular simulations are time-consuming and labor-intensive, which no longer meet the requirements of new materials development. With the rapid advances of artificial intelligence and materials informatics, machine learning algorithms are increasingly applied in materials science, aiming to shorten the development period of new materials. With the evolution of polymeric materials, the structure of polymers has become more and more complex. Traditional machine learning algorithms often do not perform satisfactorily when dealing with complex data. Presently, deep learning algorithms, including deep neural networks, convolutional neural networks, generative adversarial networks, recurrent neural networks, and graph neural networks, show their uniquely excellent learning capabilities for large and complex data, which will be a powerful tool for the design and development of polymeric materials. This Review introduces principles of several currently popular deep learning algorithms and discusses their multiple applications in the materials field. Applications range from property prediction and molecular generation at the molecular level to structure identification and material synthesis in polymers. Finally, future challenges and opportunities for the application of deep learning in polymeric materials are discussed.

Abstract:

Many therapeutic agents have failed in their clinical development, due to the toxic effects associated with non-transformed tissues. In this context, nanotechnology has been exploited to overcome such limitations, and also improve navigation across biological barriers. Amongst the many materials used in nanomedicine, with promising properties as therapeutic carriers, the following one stands out: biodegradable and biocompatible polymers. Polymeric nanoparticles are ideal candidates for drug delivery, given the versatility of raw materials and their feasibility in large-scale production. Furthermore, polymeric nanoparticles show great potential for easy surface modifications to optimize pharmacokinetics, including the half-life in circulation and targeted tissue delivery. Herein, we provide an overview of the current applications of polymeric nanoparticles as platforms in the development of novel nanomedicines for cancer treatment. In particular, we will focus on the raw materials that are widely used for polymeric nanoparticle generation, current methods for formulation, mechanism of action, and clinical investigations.

Nowadays, plastic contamination worldwide is a concerning reality that can be addressed with appropriate society education as well as looking for innovative polymeric alternatives based on the reuse of waste and recycling with a circular economy point of view, thus taking into consideration that a future world without plastic is quite impossible to conceive. In this regard, in this review, we focus on sustainable polymeric materials, biodegradable and bio-based polymers, additives, and micro/nanoparticles to be used to obtain new environmentally friendly polymeric-based materials. Although biodegradable polymers possess poorer overall properties than traditional ones, they have gained a huge interest in many industrial sectors due to their inherent biodegradability in natural environments. Therefore, several strategies have been proposed to improve their properties and extend their industrial applications. Blending strategies, as well as the development of composites and nanocomposites, have shown promising perspectives for improving their performances, emphasizing biopolymeric blend formulations and bio-based micro and nanoparticles to produce fully sustainable polymeric-based materials. The Review also summarizes recent developments in polymeric blends, composites, and nanocomposite plasticization, with a particular focus on naturally derived plasticizers and their chemical modifications to increase their compatibility with the polymeric matrices. The current state of the art of the most important bio-based and biodegradable polymers is also reviewed, mainly focusing on their synthesis and processing methods scalable to the industrial sector, such as melt and solution blending approaches like melt-extrusion, injection molding, film forming as well as solution electrospinning, among others, without neglecting their degradation processes.

Abstract:

Hemorrhage is one of the greatest threats to life on the battlefield, accounting for 50% of total deaths. Nearly 86% of combat deaths occur within the first 30 min after wounding. While external wound injuries can be treated mostly using visual inspection, abdominal or internal hemorrhages are more challenging to treat with regular hemostatic dressings because of deep wounds and points of injury that cannot be located properly. The need to treat trauma wounds from limbs, abdomen, liver, stomach, colon, spleen, arterial, venous, and/or parenchymal hemorrhage accompanied by severe bleeding requires an immediate solution that the first responders can apply to reduce rapid exsanguinations from external wounds, including in military operations. This necessitates the development of a unique, easy-to-use, FDA-approved hemostatic treatment that can deliver the agent in less than 30 s and stop bleeding within the first 1 to 2 min at the point of injury without application of manual pressure on the wounded area.

Abstract:

In the foreseeable future, the development of petroleum-based polymeric materials may be limited, owing to the gradual consumption of disposable resources and the increasing emphasis on environmental protection policies. Therefore, it is necessary to focus on introducing environmentally friendly renewable biobased materials as a substitute for petroleum-based feed stocks in the preparation of different types of industrially important polymers. Plant polyphenols, a kind of natural aromatic biomolecule, exist widely in some plant species. Benefiting from their special macromolecular structure, high reactivity, and broad abundance, plant polyphenols are potent candidates to replace the dwindling aromatic monomers derived from petroleum-based resources in synthesizing high-quality polymeric materials. In this review, the most related and innovative methods for elaborating novel polymeric materials from plant polyphenols are addressed. After a brief historical overview, the classification, structural characteristics, and reactivity of plant polyphenols are summarized in detail. In addition, some interesting and innovative works concerning the chemical modifications and polymerization techniques of plant polyphenols are also discussed. Importantly, the main chemical pathways to create plant polyphenol-based organic/organic–inorganic polymeric materials as well as their properties and possible applications are systematically described. We believe that this review could offer helpful references for designing multifunctional polyphenolic materials.

Abstract:

In the agro-complex, as well as in other sectors, the use of polymeric materials is one possible way forward in the innovation and development of machines and their parts. However, machine products place high demands on the materials from which they are made. Polymeric materials are currently able to compete in certain areas where metallic material would traditionally be used; however, one of their limiting characteristic is their ability to withstand elevated temperatures. This paper describes the hardness of polymeric materials when influenced by heat, generated during the double body abrasion. The paper also describes the abrasive wear of both polymers and polymeric composite systems, as well as cast iron, used in agricultural production. Heat intensity during the two-body abrasion results in a 28% fall of the composite systems hardness, to 18% fall of the Polyamid 6 hardness and to 13% fall of the Murtfeld hardness.

Abstract:

Infections caused by bacteria are one of the main causes of mortality in hospitals all over the world. Bacteria can grow on many different surfaces and when this occurs, and bacteria colonize a surface, biofilms are formed. In this context, one of the main concerns is biofilm formation on medical devices such as urinary catheters, cardiac valves, pacemakers or prothesis. The development of bacteria also occurs on materials used for food packaging, wearable electronics or the textile industry. In all these applications polymeric materials are usually present. Research and development of polymer-based antibacterial materials is crucial to avoid the proliferation of bacteria. In this paper, we present a review about polymeric materials with antibacterial materials. The main strategies to produce materials with antibacterial properties are presented, for instance, the incorporation of inorganic particles, micro or nanostructuration of the surfaces and antifouling strategies are considered. The antibacterial mechanism exerted in each case is discussed. Methods of materials preparation are examined, presenting the main advantages or disadvantages of each one based on their potential uses. Finally, a review of the main characterization techniques and methods used to study polymer based antibacterial materials is carried out, including the use of single force cell spectroscopy, contact angle measurements and surface roughness to evaluate the role of the physicochemical properties and the micro or nanostructure in antibacterial behavior of the materials.

Abstract:

Abstract The increasing concern regarding hazardous fires related to polymeric materials has prompted numerous research into eco-friendly flame retardants. in recent years metal-organic Frameworks (MOFs) have emerged as promising flame-retardant materials, characterized by metal-containing units linked to organic linkers to create strong and porous crystalline frameworks. The organic ligands make MOFs possess significant surface area and adsorption properties desirable for different applications including flame retardancy. This paper gathers many of the recently published to discuss the use performance of polymer composites with MOFs for flame retardancy in comparison with polymeric composite materials without MOFs. Besides, a comparison based on mechanical, physical, and thermal properties shows the effect of MOF on the total effectiveness of the polymeric composite materials. This paper is of great interest to both the readers involved in the sphere of heat-resistance materials, encompassing contemporary advanced composite materials used for dampening hazardous fires. Furthermore, prospective trends, including the integration of innovative fillers such as MOFs in rubber composites such as NBR (Nitrile Butadiene Rubber), EPDM (Ethylene Propylene Diene Monomer), and silicone rubber, are deliberated upon.

Abstract:

Polymeric materials, renowned for their lightweight attributes and design adaptability, play a pivotal role in augmenting fuel efficiency and cost-effectiveness in railway vehicle development. The tailored formulation of compounds, specifically designed for additive manufacturing, holds significant promise in expanding the use of these materials. This study centers on poly(lactic acid) (PLA), a natural-based biodegradable polymeric material incorporating diverse halogen-free flame retardants (FRs). Our investigation scrutinizes the printability and fire performance of these formulations, aligning with the European railway standard EN 45545-2. The findings underscore that FR in the condensed phase, including ammonium polyphosphate (APP), expandable graphite (EG), and intumescent systems, exhibit superior fire performance. Notably, FR-inducing hydrolytic degradation, such as aluminum hydroxide (ATH) or EG, reduces polymer molecular weight, significantly impacting PLA’s mechanical performance. Achieving a delicate balance between fire resistance and mechanical properties, formulations with APP as the flame retardant emerge as optimal. This research contributes to understanding the fire performance and printability of 3D-printed PLA compounds, offering vital insights for the rail industry’s adoption of polymeric materials.

Abstract:

To obtain biomaterials with the potential for use in the treatment of first-burn injuries, this study focused on the development of several polymeric systems based on collagen-polyvinyl alcohol-active principles. The hydrogels were prepared using polymeric matrices formers (collagen and polyvinyl alcohol), water, and glycerol in the presence of the nonionic surfactant polysorbate 80 (Tween 80®) under proper homogenization. For the development of multifunctional textile materials designed for topical application, ciprofloxacin, chlorhexidine, tea tree essential oil, and curcumin were used as active principles. The obtained hydrogels were then immobilized by the padding method on 100% plain weave cotton. The functionalized textile materials were characterized in terms of their physico-mechanical and comfort characteristics, hydrophilicity, and antibacterial activity. The mass of all the functionalized textile materials increased compared to that of the untreated fabric, due to the amount of polymeric systems remaining after the functionalization process. The water vapour permeability and air permeability of the functionalized materials were lower than those of the untreated samples. Antibacterial activity was observed for all analysed samples, with inhibition zones between 14 mm (CUC-11 code in the presence of S. aureus) and 27 mm (CUC-1 code in the presence of E. coli), obtained for the textile materials treated with the hydrogels containing ciprofloxacin, exhibiting the most pronounced antibacterial effect compared to analogous samples containing chlorhexidine. The obtained experimental data suggest that these hydrogels are appropriate candidates for application in burn wound management.
