Abstract:

This study investigates the potential of gelatin films as a biodegradable material for food preservation and heavy metal ion removal. Gelatin, a biodegradable protein derived from animal collagen, was dissolved in distilled water to form a solution and casted to form films. The films were evaluated for their swelling behavior, solubility in food, moisture content, thickness, and biodegradability. The results showed that gelatin films were completely soluble in water within 3 hours, with a water solubility of 29 ± 1.6%. The films showed UV-visible light absorbance ranging from 280 to 480 nm wit

Abstract:

The modern aspects of some rheological characteristics of polymeric materials obtained using starch of substandard wheat grains and sugar beet pulp are considered. The main factors affecting mixing are discussed, which ensures high-quality dispersion and distribution of particles in the matrix in order to obtain a homogeneous mixture and the required properties of biopolymers. A study on the selection of the percentage ratio of fillers (starch and sugar beet pulp) allowed us to develop compositions for biodegradable films. The main objective of the research is to reduce the biodegradation peri

Abstract:

The biodegradable polymers are widely used in therapeutic surgery and pharmaceutics, in which the degradation process has drawn significant attention in recent years. In this paper, we propose a mathematical model to predict the polymer degradation in tissue engineering applications. A stochastic model is introduced to characterize the hydrolysis reaction in an elemental basis and the mass transport is also performed to investigate the diffusive transport of polymer erosion. Two representative polymeric films in different configurations are studied. It is found that for biodegradable systems,

The microbial biodegradation of new PLA and PCL materials containing birch tar (1–10% v/v) was investigated. Product of dry distillation of birch bark (Betula pendula Roth) was added to polymeric materials to obtain films with antimicrobial properties. The subject of the study was the course of enzymatic degradation of a biodegradable polymer with antibacterial properties. The results show that the type of the material, tar concentration, and the environment influenced the hydrolytic activity of potential biofilm degraders. In the presence of PCL films, the enzyme activities were higher (excep

Abstract:

The principle of breathable food packaging is to provide the optimal number of pores to transfer a sufficient amount of fresh air into the packaging headspace. In this work, antimicrobial microporous eco-friendly polymeric membranes were developed for food packaging. Polylactic acid (PLA) and polycaprolactone (PCL) were chosen as the main packaging polymers for their biodegradability. To develop the microporous films, sodium chloride (NaCl) and polyethylene oxide (PEO) were used as porogenic agents and the membranes were prepared using solvent-casting techniques.

Abstract:

Applications of cyanoacrylate monomers are generally limited to adhesives/glues (instant or superglues) and forensic sciences. They tend to polymerize rapidly into rigid structures when exposed to trace amounts of moisture. Transforming cyanoacrylate monomers into transparent polymeric films or coatings can open up several new applications, as they are biocompatible, biodegradable and have surgical uses. Like other acrylics, cyanoacrylate polymers are glassy and rigid. To circumvent this, we prepared transparent cyanoacrylate films by solvent casting from a readily biodegrade solvent, cyclopen
