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: Poly(butylene succinate) (PBS), a bio-based and biodegradable polymer, was synthesized using immobilized Candida antarctica Lipase B as a biocatalyst in a solvent-free process. The process parameters were optimized to obtain PBS with desired molecular weight and thermal properties. The post-polymerized PBS was used as a carrier for the natural antioxidant flavonoid naringin, demonstrating its potential as an effective encapsulation system.

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: This study presents two strategies to regulate the enzymatic degradation of PBS films. One is to add multilayer coats of polysaccharide alginate and chitosan to the PBS films, and the other is to embed lipase-filled alginate particles in the PBS films. The results show that the number of protective coating layers and the amount of encapsulated enzyme affect the degradation extent of PBS films.

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 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: The effects of different processing parameters on a blend of PBS and PBAT were studied using an internal mixer connected to a torque rheometer. The rheological, structural and thermomechanical properties of the resulting blends were analyzed. The results showed that lower temperature and screw rotation favored transesterification, as indicated by the tensile strength tests and FTIR spectra. The blends processed at lower temperature, screw rotation, and extended mixing time exhibited higher storage modulus and complex viscosity values, indicating improved thermomechanical and rheological properties without significant changes in blends' crystallinity.

Summary: The development of biodegradable and compostable materials, such as polybutylene succinate (PBS), as alternatives to fossil-based plastics is highly important. PBS is a compostable aliphatic polyester with good mechanical strength and thermal resistance. However, it is often blended with other polymers, fillers, and additives to improve processability and mechanical performance. Recent advances in polymer blending processes have made PBS blends an interesting material platform for applications requiring a balance of mechanical strength, flexibility, thermal resistance, and compostability.

Summary: This study reports the synthesis of novel dually crosslinked covalent adaptable networks (CAN) using a single biobased building block, 2,5-furandicarboxaldehyde (FDC), to obtain dynamic associative imine linkages and dissociative Diels-Alder adducts. The linear polyimine based on FDC showed fast coupling with maleimides in Diels-Alder reactions, leading to the rapid formation of polymer networks. The resulting sustainable polymer systems exhibited behavior intermediate to vitrimers and dissociative CANs, with tunable mechanical behavior and excellent reprocessability.

Summary: In the past two decades, covalent adaptable networks (CANs) have emerged as an important class of polymer materials that combine the benefits of thermoplastics and thermosets. These materials can undergo repeated processing cycles by incorporating dynamic covalent bonds within a cross-linked network. By integrating renewable resources, such as lignins, into these innovative systems, sustainable materials can be developed in line with the circular bioeconomy. By modifying lignin into liquid polyols and polyacetoacetates, an innovative strategy was developed to create recyclable lignin-based vinylogous urethane (VU) networks with tunable structures and properties. These biobased aromatic vitrimers exhibited fast stress-relaxations, allowing for easy and fast mechanical reprocessing, and demonstrated healing ability, enhancing their lifecycle and sustainability.

Summary: This study focuses on the synthesis and structure-property relationships of sustainable aromatic TPUs derived from different potential sustainable resources. The presence of aromatic rings enhances phase segregation and improves thermo-mechanical and mechanical properties. Conversely, methoxy groups and the asymmetry of the aromatic diisocyanate hinder the organization of the hard segments, leading to reduced structuration and lower mechanical properties of TPUs.
