Abstract:
Two bio-based polyols (Polyol-r and Polyol-t) were synthesized from commercially available epoxidized soybean oil (ESBO). Polyol-r was obtained from ring opening of ESBO in the presence of fluoboric acid, while Polyol-t from a transesterification of Polyol-r with glycerol through a litharge catalyst. A rigid polyurethane foam was prepared by mixed polyols (Polyol-t and commercial 635 polyether polyol) with 4,4'-methylene-bis (phenyl isocyanate). The hydroxyl value of Polyol-t was higher than that of Polyol-r, which was also backed up by Fourier transform infrared spectrometry. Scanning electro

Abstract:
Currently, most commercial polyols used in the production of polyurethane (PU) foam are derived from petrochemicals. To address concerns relating to environmental pollution, a sustainable resource, namely, castor oil (CO), was used in this study. To improve the production efficiency, sustainability, and compressive strength of PU foam, which is widely used as an impact-absorbing material for protective equipment, PU foam was synthesized with CO-based multifunctional polyols. CO-based polyols with high functionalities were synthesized via a facile thiol-ene click reaction method and their chemi

Abstract In this article, five kinds of soybean oil-based polyols (polyol-E, polyol-P, polyol-I, polyol-B, and polyol-M) were prepared by ring-opening the epoxy groups in epoxidized soybean oil (ESO) with ethyl alcohol, 1-pentanol, isoamyl alcohol, p-tert-butylphenol, and 4-methoxyphenol in the presence of tetrafluoroboric acid as the catalyst. The SOPs were characterized by FTIR, 1H NMR, GPC, viscosity, and hydroxyl numbers. Compared with ESO, the retention time of SOPs is shortened, indicating that the molecular weight of SOPs is increased. The structure of different monomers can significant

It is well known that the traditional synthetic polymers, such as Polyurethane foams, require raw materials that are not fully sustainable and are based on oil-feedstocks.

Polyurethanes are a class of materials which can be regarded as filling the gap between rubbery elastomers and rigid plastics and metals. They can exhibit both high elongation and resilience, while retaining high modulus which make them unique for a wide variety of applications in which both stiffness and extensibility is needed. It is now widely accepted that the diverse properties of these copolymers are attributed to the existence of a two phase microstructure. One phase is regarded as a glassy or hard segment, whereas the other phase is considered to be rubbery and to give soft segments. T

Abstract:
Polyurethanes can be used in many applications by modifying their properties via facile methods. Most of the polyurethanes currently used for industrial applications originated from petrochemical-based chemicals. There is a growing demand in industries to use renewable resources for polyurethanes. Vegetable oil-based polyurethanes have shown properties comparable to that of petroleum-based polyurethanes. In this research, sunflower oil was used as a renewable resource for polyurethanes. Rigid polyurethane foams were prepared using sunflower-based polyols. The polyols were synthesized via epoxi

Abstract:
Polyurethane, as a versatile polymer prepared by the polyaddition of isocyanates and hydroxyl group containing compounds, is widely used in the automotive industry and with an upcoming change of European legislation becomes recycling increasingly important as an alternative to landfilling or incineration. Glycolysis is one of the chemical degradation processes used to transform polyurethane waste using simple glycols as the degradation agents into a raw material. Single phase glycolysis was used to produce recycled polyol from polyurethane semi-rigid foam dedicated for headliner production. Th

Abstract:
Poliovirus is the causative agent of poliomyelitis, a potentially debilitating disease that is a target for global eradication. Vaccination against poliomyelitis is an important tool in the eradication effort, but one of the available vaccines, the oral poliovirus vaccine, contains live, attenuated strains that can revert to virulent forms. Community transmission of so-called vaccine-derived polioviruses (VDPVs) can contribute to outbreaks, including in areas with no recently reported poliomyelitis cases. Wastewater-based surveillance (WBS) is a widely applied method to monitor communities for

Abstract:
The objective of this study is to develop a new conductive thermoplastic material with superior electrical properties. Currently, conductive polymers are typically filled with carbon or metallic particles [1]. However, these filled thermoplastics exhibit drawbacks such as high rigidity, toxicity, and high viscosity [2]. An alternative approach investigated in this work is to substitute these fillers with intrinsically conductive polymers like Poly(3,4-ethylenedioxythiophene) (PEDOT). PEDOT can achieve exceptional electrical conductivities (over 1000 S.cm-1) when combined with polymeric dopants
