Summary: In this study, PHB and TEC were blended to investigate the effects of TEC as a plasticizer on the properties of PHB. Increasing the mass fraction of TEC led to gradual changes in mechanical, thermal, and morphological properties of PHB, with TEC acting as an efficient plasticizer. The presence of TEC reduced the glass transition and melting temperatures of PHB, expanded the processing window of temperature, and influenced the crystallization kinetics and morphology of PHB.

Summary: In this work, PHBV composites were prepared using TEC as a biodegradable plasticizer and SBF as reinforcement via melting extrusion. TEC reduced the viscosity and thermomechanical degradation of PHBV, while SBF acted as a nucleation agent for PHBV crystallization and enhanced the tensile properties of the matrix. TEC and SBF had antagonistic effects on the properties of the composites, providing opportunities for property tuning by varying the composition.

Summary: Due to the hydrophobic nature of the fluorocarbon backbone, Nafion membranes are preferred for high H+ conductivity. However, they are limited by a higher price, pH splitting, and bio-fouling, leading researchers to search for better alternatives. Conducting polymers like polyaniline and polypyrrol can be used as electrolyte membranes for fuel cells, and their conductivity can be enhanced through doping techniques. This review provides a detailed discussion on these conducting polymers and their applications, particularly in composite membranes, and evaluates their effects on methanol crossover, H+-conductivity, gas diffusion, and thermal stability for practical DMFC applications.
