Special Issue Information

Dear Colleagues,

Polyester is one of the most important kind of polymers widely applied in our daily life and industry. However, the traditional polyesters are faced with various problems, such as lack of biodegradability and function, and their mechanical properties are insufficient for some special applications. This Special Issue focuses on the investigation of the synthesis, structure, and properties of functional polyester and high-performance polyesters. Functional polyesters of poly(L-lactic acid), poly(butylene succinate), polycaprolactone, poly(butylene adipate terephthalate), poly(p-dioxanone), polyglycolide, and poly(lactic-co-glycolic acid), such as biodegradable, biocompatible, and bioresorbable polyester, or polyesters with special functions, such as antibacterial properties, gas barrier, ultraviolet shielding, anti-fouling; chromatophilic, shape memory, self-cleaning, and self-healing, are chief points in this Issue. High-performance polyesters, such as highly transparent, heat-resistant, high strength, high modulus, and highly ductile, are also a major focus of this Special Issue.

In response to the escalating plastic pollution crisis, the development of high-performance biodegradable materials is critical. Poly(butylene succinate) (PBS) is an important biodegradable polymer as it possesses excellent biodegradability and processability. But it suffers from limitations such as low mechanical strength, poor thermal stability, and high production costs. In this study, taxus residue (TF), a waste by-product, was utilized as a reinforcing filler to reduce PBS costs while enhancing its overall performance. To address the interfacial incompatibility between TF and PBS, branched PBS (T-PBS) was introduced as a compatibilizer. The TF was surface-modified via alkali treatment and silane coupling (KH550), and a series of PBS/TF/T-PBS composites with varying T-PBS viscosity grades were prepared by melt blending. The compatibilization mechanism of T-PBS and its influence on the composite structure, crystallization behavior, thermal stability, rheological, and mechanical properties were systematically investigated. Results show that the branched structure significantly enhanced T-PBS melt strength and reactivity. The introduction of T-PBS effectively improved interfacial compatibility between TF and PBS matrix, reducing phase separation and interfacial defects. Compared to uncompatibilized PBS/TF composites, those with appropriately viscous T-PBS exhibited improved tensile strength (increased by 19.7%) and elongation at break (increased by 78.8%), while flexural strength was also maintained at an enhanced level. The branched points acted as nucleating agents, increasing the onset temperature and degree of crystallinity. In the high-temperature region, the synergistic barrier effect from TF and char residue improved thermal stability (T85% reached 408.19 °C). Rheological analysis revealed enhanced viscosity and elasticity of the system. This study provides a promising strategy and theoretical foundation for the high-value utilization of taxus waste and the development of high-performance biodegradable PBS-based composites.
