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: Biodegradable polymers, such as poly(butylene succinate) (PBSu) biocomposites, containing biochar (BC) filler can improve mechanical properties, thermal transitions, and biodegradability. The addition of BC enhances tensile and impact strengths, facilitates crystallization, and increases thermal diffusivity and conductivity. However, it also causes an increase in overall dielectric permittivity. Furthermore, the enzymatic hydrolysis degradation rate of biocomposites is found to increase with increasing BC content.

Summary: Biocomposites based on PBS and OMt were prepared by melt blending process. Gemini surfactant-modified organoclays showed a uniform dispersion and exfoliation in the PBS matrix, leading to improved properties. Adding a small amount of PBS/OMt significantly reduced the water vapor permeability, making it a promising material for food packaging applications.

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: PLLA and PBS are biodegradable, compostable, and biocompatible polymers that have complementary properties, making blending them an opportunity to exploit their favorable characteristics. However, research on the properties of PLLA/PBS blends has yielded contradictory results, creating complexity in their utilization.

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 experimentally synthesized bamboo fiber-reinforced biocomposites using bamboo fiber as filler and PBS as biodegradable polymer matrix. The research found that treated BF increased the tensile strength of the biocomposites, while higher BF content led to decreased elongation at break and increased Young's modulus. The biocomposites are suitable for packaging and indoor furniture parts.

Summary: Fast hydrolyzable polyesters are a promising solution to plastic pollution and microplastic issues, with aromatic polyesters being mechanically strong but nonbiodegradable, and aliphatic polyesters being the opposite trend. A new aliphatic polyester, poly(1,4-benzenedimethylene succinate) (PBDMS), and its copolymers (PBxBDMyS), have been proposed in this work, demonstrating balanced mechanical, thermal, and hydrolysis properties.

Summary: This study focused on the development and characterization of biocomposites based on a fully bio-based polyester, PBSA, and wheat bran. The composites maintained similar processability and mechanical properties to virgin PBSA with up to 15 wt.% bran content. The biodegradation tests showed bran's capacity to improve the PBSA biodegradation rate, likely due to the hygroscopic bran swelling and increased polymeric matrix-seawater interfacial area.

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 effects of poly(butylene-succinate) (PBS) and cassava pulp (CP) at different particle sizes on the properties of PBS/CP biocomposites. The results showed that the addition of CP improved the hardness and Young's modulus of the biocomposites, but decreased their tensile strength and impact strength. The use of CP with a particle size of 250 μm resulted in better particle dispersion and compatibility. A CP content of 40% showed the best biodegradability.

Summary: A novel PBS-b-PA4 diblock copolymer was designed and synthesized in this study, with its chemical structure, self-assembly behavior, and emulsifying properties characterized through various experiments. The copolymer formed micelle-like colloidal particles in chloroform and exhibited birefringent and fluid liquid crystalline phase in 1,1,2,2-tetrachloroethane, demonstrating potential as a compatibilizer for binary resin blends.

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: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
