Summary: This study investigated the use of micro-nano rice husks (MNRH) fibers compounded with polylactic acid (PLA) to produce 3D-printed filaments. The addition of silane coupling agents improved the surface quality and enhanced the dispersing performance of the MNRH fibers in the composites. The treated composites exhibited improved thermal stability, crystallinity, and water resistance. Furthermore, the mechanical properties of the composites, including tensile strength and bending strength, were significantly enhanced. The findings suggest that the treated composites have great potential for use as environmentally friendly alternative materials in automotive interiors.

Summary: The study found that the type and amount of hardener significantly affect the curing reaction and performance characteristics of epoxidized linseed oil, with the optimal mixing ratio needing to be experimentally determined rather than calculated. The investigated thermosets exhibit different glass transition temperatures and mechanical performances after curing, ranging from soft and flexible to stiff and rigid.

Summary: This study investigates the effect of gamma radiation on the interaction between kraft lignin and PBAT/PLA blend. The results show that irradiation promotes the miscibility and compatibility of PBAT/PLA/lignin. The crystallization peak of PBAT/PLA/lignin shifts to lower temperatures and the crystallization rate decreases after irradiation.

Summary: This paper synthesized poly(butylene succinate-co-diethylene glycol succinate) (PBSD) copolymers to improve the nonenzymatic hydrolysis of poly(butylene succinate) (PBS). The results showed that the contact angle and water uptake of the copolymer increased significantly, indicating microphase separation occurred. PBSD copolymers exhibited high tensile strength, elongation at break, and decomposition temperature. The weight loss of PBSD copolymers was greater in acidic conditions compared to neutral conditions and simulated seawater. PBSD copolymers have the potential to be utilized as water degradable materials for environmental pollution control.

Summary: This work presents the development of a bio-based polymer blend, PVA/CG, embedded with boehmite nanoparticles to enhance its structural, thermal, mechanical, and electrical properties. The presence of boehmite in the blend was confirmed through FTIR and XRD analysis. SEM images showed uniform dispersion of boehmite at 5 wt%. The addition of boehmite increased the thermal stability and electrical conductivity of the blend, while slightly decreasing the glass transition temperature. Tensile strength and hardness improved with the incorporation of boehmite, making the PVA/CG/boehmite films a potential substitute for flexible electronic and electrochemical devices.

Summary: Polyesters with high T-g from renewable resources are crucial for expanding their application range. A series of copolyesters, PBSF, were synthesized from BHEPS, BDO, and FDCA, with increasing BHEPS content leading to higher T-g but lower M-w. PBSF-65 was identified as a promising polyester for various applications requiring high transparency and heat resistance, with specific properties suitable for baby bottles, children's toys, kitchen appliances, and beverage packaging.

Summary: This study investigates the impact of dispersed aluminum (Al) and copper (Cu) nanoparticles on the thermophysical properties of paraffin wax. The results show that the dispersion of nanoparticles can decrease the melting temperature and increase the solidification temperature of paraffin wax. However, it also increases the dynamic viscosity and limits the dispersion. Moreover, the nanocomposites with mass fractions of 2% Al and 1% Cu exhibit better enhancements in thermal storage characteristics compared to higher mass fractions.
