Summary: The effects of hydrothermal aging on wood flour-poly(butylene succinate)-poly(lactic acid) biocomposite samples were studied. Modification with glycerol and KH550 improved the performance of the samples, while hydrothermal aging had negative effects. The modified samples exhibited better resistance to hydrothermal aging.

Summary: UV absorber-modified PBST films show improved weathering resistance and can be used to manufacture agricultural films according to natural weathering studies conducted in Xinjiang and Hainan, China. The significant deterioration of toughness in the transverse direction is an important factor contributing to the decreased serviceability of the films after weathering. These findings provide guidance to increase the weathering resilience of PBST films, which can be utilized to efficiently and economically fabricate agricultural films.

Summary: To address the plastic deformation issue of biodegradable fibers, a solvent-free melt spinning method was developed to prepare poly(butylene succinate)/microcrystalline cellulose (PBS/MCC) composite monofilaments. The high modulus and rigidity of MCC limited the plastic deformation of PBS, and the in-situ formed hydrogen bonds between MCC and amorphous PBS improved MCC dispersion and created rigid MCC physical crosslink points. The composite monofilaments, with the addition of 10-25 wt% MCC and subjected to multi-stage and high-ratio hot stretching, exhibited double yielding behavior and microelastic response, indicating resistance to permanent deformation under small strain. Furthermore, the inclusion of MCC improved the biodegradability of the composite monofilaments after being buried in soil for 60 days.

Summary: Aliphatic and aliphatic-aromatic polyesters are widely used in food packaging, with a particular focus on volatile organic compounds (VOCs). This study utilized various analytical techniques to investigate the presence of cyclic esters, a type of VOC, in poly (butylene succinate) (PBS) and poly (butylene adipate-co-terephthalate) (PBAT). The results showed that the cyclic esters varied in repeating unit length and were influenced by different reaction conditions.

Summary: The research investigated the effects of cellulose fiber addition on the properties of PLA/PBS/CF composite materials, showing that the addition of cellulose fiber can enhance the strength and thermal resistance of the composites. As the amount of cellulose fiber increased, the tensile strength, tensile modulus, and percentage of elongation at break also increased.

Summary: Green poly (butylene succinate) (PBS) composites are prepared by melt blending with gamma-Glycidoxypropyltrimethoxysilane (KH560) grafted rice husk (RH), namely RH@KH560, improving the toughness and strength of the materials. The incorporation of 15% RH@KH560 into the composite increases the modulus by 223% and the Izod impact strength by 143%. Differential scanning calorimetry results show a decrease in crystallinity of PBS composite by 22% when the amount of RH@KH560 is 30%. The melting enthalpy of the composite gradually decreases, indicating a significant reduction in crystallinity. Overall, recycling waste rice husk as valuable additives is proposed as a facile strategy.

Summary: Dual-layer membranes of poly(lactic acid) and poly(butylene succinate) filled with cellulose nanowhisker were fabricated for removing metal ions from wastewater. The addition of nanowhisker improved membrane porosity and filtration performance, but could affect heat resistance. In continuous operation tests, the 3% CNW filled membrane showed the highest removal efficiency for cobalt and nickel metal ions.

Summary: This research investigated the effect of cellulose nanocrystals (CNC) on the crystallization behavior, crystalline morphology, and crystal structure of Poly(ethylene succinate-co-1,2-propylene succinate) (PEPS). The results showed that CNC enhanced the crystallization rate of PEPS and acted as a heterogeneous nucleating agent. The induction of CNC played an important role in the nucleation mechanism of PEPS.

Summary: In this study, cellulose nanocrystals (CNCs) were treated with ethyl succinyl chloride to improve their compatibility with poly (butylene succinate) (PBS). Melt spinning and heat stretching were used to prepare PBS/CNC fibers with enhanced orientation and mechanical properties. The effects of CNC modification on chemical structure, wettability, dispersion, thermal properties, and mechanical properties were systematically investigated. The stretching treatment significantly affected the dispersion, alignment, and thermal behavior of CNCs, as well as the orientation of PBS chains. The formation of a multidimensional oriented superstructure, including regularly arranged PBS shish kebab crystals, modified CNCs, and oriented PBS chains, was suggested in the composite fibers prepared at high draw ratio. The high draw ratio resulted in a significant improvement in tensile strength.

Summary: A facile synthesis methodology was developed to graft ionic liquids onto hydroxyethyl cellulose (HEC) ester, resulting in biocompatible and biodegradable HEC-ILs with attractive properties such as high degree of substitution, solubility in water, and permanent positive charge. The synthesized HEC-ILs were characterized by various techniques and their potential applications in drug delivery and anionic molecule complexation were explored.

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: 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.
