Summary: This study evaluates the effects of grape seed extract incorporation, addition order, and concentration in chitosan and gelatin solutions on rheological parameters. The addition order has a direct influence on rheological properties, and low extract concentrations result in solutions suitable for coating applications. Standardizing the addition procedures during material preparation is essential based on the findings of this study.

Summary: The molecular structure of polylactic acid (PLA) was modified by lauroyl peroxide (LP) as an alkyl free radical and glycidyl methacrylate (GMA) as a reactive co-monomer. Different preparation methods resulted in samples with varying rheological properties and crystallization degrees, indicating the impact of preparation methods on the physical and mechanical properties of glycidyl methacrylate grafted polylactic acid (PLA-g-GMA).

Summary: This paper demonstrates the re-processability and mechanical strength recovery of low T-g TE vitrimers without the use of catalysts or special designs. Through compressive remolding, the vitrimers can repair defects and restore mechanical strength within a short period of time. Mechanical recycling does not significantly affect the mechanical properties of the vitrimers. Stress relaxation experiments confirm the network rearrangement and vitrimeric flow of the materials at high temperatures.

Summary: The study investigated the effects of various shapes and addition amounts of crosslinking reagents on the expression mechanisms of polymer properties in PHB and PCL blends. It was found that the elasticity of the blends increased with the addition of liquid crosslinking reagents, while the toughness decreased with the addition of solid crosslinking reagents.

Summary: Blending high content of polyhydroxyalkanoates (PHAs) and polylactide (PLA) significantly improves the heat resistance of PLA fibers, but maintaining good spinnability remains a challenge. This study successfully fabricates PLLA/P34HB blend fibers with low P34HB content and excellent spinnability. The incorporation of P34HB greatly improves the heat resistance of the blend fibers by increasing the crystallinity of PLLA.

Summary: The study involved using mixtures of two sustainable liquid surfactants with different hydrophilic-lipophilic ratios to compatibilize blends of poly(lactic acid) and low-density polyethylene. The compatibilization significantly altered the microstructure, reducing particle size and increasing dynamic elastic modulus in virgin polymer-based blends. However, the efficiency of the selected compatibilizers varied in reprocessed polymer-based blends, showing different effects on microstructure compared to noncompatibilized blends.

Summary: This study reports the compatibilization of thermoplastic starch (TPS)/polylactic acid (PLA) blends with a glycerol ester (GE). The addition of GE improved the light transmission resistance of the blends and decreased the glass transition temperature and complex viscosity values. The presence of GE also improved the interfacial adhesion between TPS and PLA.

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: The study found that the addition of glassy carbon filler does not negatively impact the biodegradability of PHBV, but the increase in crystallinity caused by ultraviolet radiation hindered water and enzyme access to the materials, reducing biodegradability.
