Summary: Polybutylene succinate/soy protein isolate bio-composites were compatibilized by in situ graft copolymerization with the addition of BPO and PEG400DA. The presence of the graft copolymer strengthened the interfaces and improved the water resistance and thermal stability of the composites. It also increased the viscosity, elasticity, and crystallinity of the melt.

Summary: The addition of CNC/PBS composite enhanced the crystallization ability of the PLA/PBS blends and increased the crystallinity while decreasing crystal size of the PLA phase. This led to an increase in the Young's modulus and the flexural strength of the PLA/PBS composites without compromising tensile strength and impact strength.

Summary: In order to improve the performance of biodegradable materials, Luteolin (Lc) was modified through esterification with Acetyl chloride (Ac), Iso-butyryl chloride (Ic), and Benzoyl chloride (Bc) to enhance their hydrophilicity and hydrophobicity. The esterified compounds, Ac-L, Ic-L, and Bc-L, were characterized and blended with PBS to prepare PBS/Ac-L, PBS/Ic-L, and PBS/Bc-L composites. The interface interaction mechanism, crystallization performance, thermodynamic performance, hydrophilic properties, and antibacterial performance of the composite materials were studied. The results showed that the addition of Ac-L, Ic-L, and Bc-L improved the dispersion and compatibility in the PBS matrix, increased the crystallization rate and crystallinity of the composite, and enhanced the thermal stability and mechanical properties.

Summary: In this study, high strength PVA/SPI composite hydrogels (EPSG) were constructed by introducing PVA into SPI through crosslinking and freezing-thawing processes. The results showed that EPSG hydrogels had a homogenous porous structure and the introduction of PVA greatly increased the compressive strength of SPI hydrogels. The EPSG hydrogels also exhibited good biocompatibility and hemocompatibility, making them potential materials for direct blood contact in tissue engineering applications.

Summary: This study aimed to improve the gel quality of silver carp protein (SCP) by adding soy protein isolate (SPI) and using glutamine transaminase (TG) to form a composite gel. The addition of papain-treated SPI increased the hardness, springiness, chewiness, cohesiveness, and water-holding capacity (WHC) of the protein gel. Molecular force results showed that hydrogen bonding, disulfide bonding, and hydrophobic association played important roles in gel formation. Scanning electron microscopy (SEM) analysis revealed that the papain modifications allowed the formation of a complex, continuous, and uniform gel structure.

Summary: The influence of the interaction between vitamin B-12 and soybean protein isolate (SPI) on the structure of SPI was studied. The results show that as the concentration of vitamin B-12 combined with SPI increases, the structure becomes more orderly. Raman spectroscopy analysis also indicates an increase in interaction between SPI and vitamin B-12 with higher concentration of the vitamin.

Summary: The effects of 1% (w/w) softwood kraft lignin nanoparticles (SLNPs) on the physicochemical properties of polybutylene succinate (PBS) composite films were investigated in this study. The incorporation of SLNPs into PBS enhanced its thermal stability, tensile strength, and barrier properties, while also providing antimicrobial functions. Therefore, SLNPs could be a promising alternative to synthetic substances for enhancing polymer properties without compromising biodegradability, and for active packaging applications.

Summary: In this study, intumescent flame retarded polybutylene succinate (PBS) formulations were developed using ethylenediamine phosphate (EDAP) and different co-additives. Among them, zinc borate showed the best synergistic flame retardant effect with EDAP in PBS. Analysis using solid state NMR and cone calorimetry revealed the formation of a highly thermally stable inorganic char by EDAP and zinc borate in PBS, acting as an effective flame retardant mechanism.

Summary: This study investigated the potential of using natural cellulose-based wood fiber as an untreated bio-reinforcement in polybutylene succinate composite films. The addition of the wood fiber improved the properties of the composite, but excessive amounts resulted in a decrease in performance. A formulation with 10 parts per hundred of wood fiber showed the highest mechanical strength and degradation potential.

Summary: Poly(lactic acid) (PLA) was toughened by incorporating ductile biodegradable poly(butylene succinate) (PBS) and biobased epoxidized soybean oil (ESO). The addition of a reactive reagent (Joncryl ADR 4370 S) enabled the formation of graft copolymers in situ, resulting in significantly improved compatibility and mechanical properties of the bio-blends. The study utilized various characterization techniques to investigate the compatibility, rheology, crystallization, mechanical properties, and microstructures of the bio-blends. The biodegradable and biobased supertough PLA/PBS/ESO blends exhibited excellent tensile strain at break and impact strength, attributed to the combination of ESO and 4370S.
