Summary: The degradation behavior of PBAT films by different concentrations of Fusarium solani cutinase (FsC) was investigated. It was found that FsC could degrade both the amorphous region and the crystalline region of PBAT films, and its degradation activity was concentration-dependent. High concentration of FsC resulted in significant degradation of PBAT films, while low concentration had less apparent effect. FsC concentration and degradation time did not significantly affect the molecular weight of degraded PBAT.

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: 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: Nylon fishing nets cause damage to marine environments when lost, so a biodegradable poly(butylene succinate) (PBS) resin was developed. By adding adipic acid and ethylene glycol to PBS, poly(butylene adipate-co-butylene succinate-co-ethylene adipate-co-ethylene succinate) (PBEAS) resin with excellent properties and low melting point was synthesized. This resin can be used for gill nets, expanding the application of biodegradable fishing gear.

Summary: Triboelectric nanogenerator (TENG) devices are simple and efficient systems for converting mechanical energy into electricity. However, the lack of attention to recycling or reusing TENG devices, which are mostly made of non-biodegradable polymers, leads to negative environmental impacts. Developing biodegradable triboelectric materials is crucial for sustainable use and disposal of TENG devices.

Summary: Aliphatic/aromatic thermoplastic polyesters are an interesting group of polymers with various applications. Poly(alkylene 2,5-furandicarboxylate)s (PAFs) are biobased alternatives to poly(alkylene terephthalate)s and are expected to play a crucial role in the bioeconomy. This study focuses on the solidification parameters of PAFs during processing, using poly(butylene 2,5-furandicarboxylate) (PBF) as a model material. The results show the kinetics of isothermal and dynamic melt and cold crystallization of PBF and provide insights into its crystallization behavior.

Summary: We have developed a new polyester material using biobased 1,18-octadecanedicarboxylic acid and ethylene glycol, which has a solid-state structure similar to polyethylene and comparable tensile properties to high density polyethylene (HDPE). Despite its crystallinity, high melting point and hydrophobic nature, the polyester-2,18 can be rapidly and completely hydrolytically degraded in vitro by naturally occurring enzymes. It also shows high biodegradability under industrial composting conditions and can be depolymerized by methanolysis for closed-loop recycling.

Summary: This study investigated the isothermal melt crystallization kinetics of fully biodegradable poly(ethylene succinate) (PES)/cellulose nanocrystals (CNC) composites. The results showed that low loadings of CNC significantly enhanced the crystallization rate and nucleation density of PES. When the CNC loading increased from 0.25 to 1 wt%, the crystallization rate and nucleation efficiency first increased, reached a maximum, and then decreased, demonstrating a CNC loading dependence attributed to the dispersion states of CNC in the composites.

Summary: Photocurable biomaterials that can be rapidly cured using UV light are becoming popular in advanced medical applications. By modifying the structure of coumarin and combining it with a bio-based fatty acid dimer derivative, we designed a dynamic network that can crosslink and re-crosslink under variable wave lengths of UV light. This biomaterial can be injected and cured in situ upon UV light exposure, making it suitable for future medical applications.

Summary: A library of furan-based block copolymers was synthesized via a two-step polycondensation reaction using Candida antarctica lipase B as biocatalyst. The resulting copolymers were analyzed using NMR, FTIR, and GPC. XRD, DHM, and DSC were used to study the crystallization behavior and thermal properties, while OTR was measured to verify the oxygen permeability of the furan-based copolyesters. The chain length of α,ω-aliphatic linear diols used in the synthesis had a significant effect on the material properties.
