Plastic waste accumulation is a current societal crisis. Although replacing nondegradable plastics with biodegradable alternatives is one solution to this problem, conventional biodegradable plastics have low mechanical performance and require fastidious decomposition conditions. Consequently, fulfilling the industrial requirements of processability, end-use applicability, and post-use biodegradability is difficult. Therefore, integrating mechanical robustness and enhanced degradability into a single material is critical. Herein, we introduce a fully biomass-derived poly(butylene adipate-co-furanoate) (PBAF) composite with sulfated chitin nanowhiskers prepared by in situ polymerization. This approach efficiently disperses the nanofiller in the polymer matrix and creates beneficial interactions between the nanofiller and the furan rings of the polymer, resulting in excellent material properties. A PBAF composite film loaded with 0.1 wt % nanofiller is as strong as a nondegradable engineering plastic (i.e., poly(ethylene terephthalate)) and exhibits higher tensile strength (1.6-fold), tear toughness (1.4-fold), and degradation rate (1.7-fold) than neat PBAF. A structure–performance relationship study revealed that the nanofiller is accommodated close to the furan rings of the polymer, which results in noticeable segmental mobility and structural change, whereas the benzene rings of conventional poly(butylene adipate-co-terephthalate) show negligible change due to its sturdy crystalline phase. The developed all-organic composite is a sustainable alternative to conventional plastics.

具有硫酸化几丁质纳米晶须的可持续聚（己二酸丁二醇酯-呋喃酸丁二醇酯）复合材料：协同作用导致卓越的稳健性和改进的生物降解性
塑料垃圾堆积是当前的社会危机。尽管用可生物降解的替代品代替不可降解塑料是解决这一问题的一种方法，但传统的可生物降解塑料机械性能低，需要苛刻的分解条件。因此，难以满足可加工性、最终用途适用性和使用后生物降解性的工业要求。因此，将机械强度和增强的可降解性集成到单一材料中至关重要。在此，我们介绍了一种全生物质衍生的聚（己二酸-呋喃酸丁二醇酯）（ PBAF）复合材料，该复合材料具有原位制备的硫酸化几丁质纳米晶须。聚合。这种方法有效地将纳米填料分散在聚合物基质中，并在纳米填料和聚合物的呋喃环之间产生有益的相互作用，从而产生优异的材料性能。负载 0.1 wt% 纳米填料的 PBAF 复合薄膜与不可降解工程塑料（即聚对苯二甲酸乙二醇酯）一样坚固，并表现出更高的拉伸强度（1.6 倍）、撕裂韧性（1.4 倍）和降解率（ 1.7 倍）比纯 PBAF。结构-性能关系研究表明，纳米填料靠近聚合物的呋喃环，导致明显的链段迁移率和结构变化，而传统聚己二酸丁二醇酯的苯环-对苯二甲酸酯）由于其坚固的结晶相而显示出可忽略不计的变化。开发的全有机复合材料是传统塑料的可持续替代品。
