Summary: Biodegradable polymeric open-porous foams have gained increasing interest in recent decades due to their biodegradability, porosity, and biocompatibility. In this study, biodegradable poly(butylene succinate) (PBS)/chitin nanocrystals (ChNCs) nanocomposite foams with an open porous structure were successfully fabricated using a solid-state batch foaming method. The addition of ChNCs had a positive impact on the crystallization behaviors, melt viscoelasticity, and thermal stability of diverse PBS specimens, significantly influencing the open porous structure of the foams. The strategy presented in this work could serve as a guideline for regulating and controlling open porous foams in other semi-crystalline polymer matrices.

Summary: In this work, a reverse micellization approach was used to prepare uncarbonized starch and poly(1,4-butylene succinate) hybrids, which exhibited exceptional charge storage performance after activation through protonation and incorporation of magnetite nanoparticles. The magnetite incorporated St-PBS reverse micelles showed minimized contact resistance between supercapacitor electrodes, resulting in high charge storage capacity.

Summary: The study investigated the compatibility and hydrolytic behaviors of biodegradable stereochemical polylactide (l-PLA or dl-PLA) and poly(butylene succinate) (PBS) monolayer mixtures at the air/water interface. Results showed that dl-PLA/PBS monolayer mixtures exhibited better compatibility than l-PLA/PBS monolayer mixtures, and the hydrolytic rate of compatible monolayer mixtures was slower than their arithmetic averages.

Summary: In this study, ternary blends of high content TPS, PBAT, and PBS were melt-compounded. The dispersion of PBS and PBAT minor phases improved tensile strength and elongation at break. TPS/PBS/PBAT60/10/30 blend showed good balance in strength and toughness. The morphological analysis revealed a core-shell structure. With increasing PBAT composition, changes in phase morphology and decreased values of complex viscosity and storage modulus were observed. The thermal resistance and melt flow properties were also studied.

Summary: This study investigates the effects of cellulose nanocrystals (CNC) from bamboo fiber on the properties of poly (lactic acid) (PLA)/poly (butylene succinate) (PBS) composites. The addition of CNC improves the thermal stability, tensile strength, and modulus of the composite, while reducing elongation at break.

Summary: In this study, biodegradable starch-based polymers were developed by melt-blending modified thermoplastic starch with poly(butylene succinate) blended with epoxy resin. The results showed that the mechanical properties, water resistance, morphology, and thermal stability of the starch-based polymers were improved by adding poly(butylene succinate) and epoxy resin.

Summary: PBS and PBSA were irradiated with gamma radiation up to a dose of 400 kGy, resulting in the formation of gel content. PBSA exhibited higher gel content compared to PBS. Analysis revealed that chain scission predominated over crosslinking. Branching and chain scission increased the dispersity and affected the molecular weight. NMR analysis showed the appearance of new species and changes in species with increasing dose. The thermal properties, especially crystallization temperature, were significantly affected by irradiation. Mechanical properties of both polymers were greatly reduced, making them fragile even at low doses.

Summary: This study investigated the use of cellulose nanocrystals and nanoclays as reinforcing fillers in starch ester films. The addition of nanofillers significantly improved the yield strength of the films, with enhancements of up to 112% for CNC and 173% for nanoclay. The films also showed improvements in light transmission and weight loss when compared to unfilled films.

Summary: This study explores the possibility of blending PBS and PCL with BSxCLy copolymers and systematically studies the crystallization behavior of the blends. The results show that the PBS/BS78CL22 blend exhibits good miscibility at high PBS content, while the PCL/BS15CL85 blend still displays partial miscibility at high PCL content. The BS46CL54 copolymer can crystallize in both PBS and PCL type crystals, depending on the polymeric matrix.

Summary: The fabrication and characterization of PBS films enriched with the natural polyphenolic antioxidant-quercetin were reported in this study. The addition of quercetin led to significant changes in color, opacity, and UV-blocking effect of the films, while the mechanical properties slightly decreased. The PBS-quercetin films exhibited excellent antioxidant and bactericidal activities, showing potential for active food packaging applications.

Summary: By incorporating AD units into PBS chains, the crystallization temperature and crystallinity of PBS can be depressed, while the primary nucleation capability is significantly strengthened without altering crystal modification or crystallization kinetics. The presence of specific interactions among AD units is crucial for the performance of PBSAD, and further investigation may lead to the design of superior PBS copolymers in the future.

Summary: This study aimed to develop a new and green gas-regulating packaging film to prolong the shelf life of bananas. The active gas-regulating packaging film, prepared using extrusion, included MCM-41 loaded with salicylic acid as the active agent, and PLA, PBAT, and TPS as the base materials. The film exhibited better preservation performance by retarding the decay and oxidation processes of bananas.

Summary: This study presents a method to improve the gas barrier properties and photoaging stability of PBSA by using LDH fillers. The addition of LDH fillers enhances the rigidity of the nanocomposite, improves the barrier properties to oxygen and water vapor, and increases the attractiveness of PBSA material in food packaging applications. Moreover, the presence of LDH enhances the photo-durability of PBSA-LDH nanocomposites.

Summary: In this study, the heat resistance of PBST was enhanced by blending it with PBS, using ADR-4370F as a reactive compatibilizer and TMC-300 as a nucleating agent. The compatibility between PBST and PBS improved significantly, and the mechanical properties of the blend showed great improvement. The heat resistance of the PBST/PBS-based blend was improved compared to neat PBST.

Summary: Cellulose nanofibers were obtained from Tinwa bamboo leaves and chemically modified to create hydrophobic biopolymer coatings. The coatings achieved a high contact angle of up to 141 degrees and significantly reduced water penetration speed by 94% during immersion. These results suggest that modified bamboo leaf biopolymer can effectively replace hydrophobic coatings on paper.
