Abstract

The excessive use of disposable chopsticks generates a significant amount of waste, particularly waste bamboo chopsticks (WBC). This study aims to reduce waste and enhance the value of WBC by extracting bamboo fibers and reinforcing them in a biopolymer matrix. Research on WBC/polymer composites, especially those utilizing extracted bamboo fibers in a biopolymer matrix, is limited. In this research, the bamboo fibers extracted from WBC and bamboo plant are reinforced into a biopolymer called polybutylene succinate (PBS) at varying levels from 0 to 40wt% with increments of 10wt%. The characteristics of composites made from WBC fiber and PBS are analyzed and compared with those of PBS incorporating bamboo fibers obtained directly from bamboo plants. The evaluation focuses on various aspects, including morphology, mechanical strength, thermal properties, and rheological characteristics. The results showed that introducing WBC fibers into the PBS matrix did not significantly compromise the properties or thermal stability of the composites when contrasted with bamboo fibers sourced from bamboo plants and used in PBS composites. The WBC fiber/PBS composites displayed slightly superior mechanical and rheological properties compared to composites incorporating bamboo plant fibers in PBS. The results affirm that bamboo fibers extracted from WBC can effectively reinforce biopolymer composites.

用于生物基聚丁二酸丁二醇酯复合材料加固的废弃竹筷纤维素基纤维
一次性筷子的过度使用产生了大量垃圾,尤其是废弃竹筷(WBC)。本研究旨在通过提取竹纤维并将其强化在生物聚合物基质中,从而减少废弃物并提高废弃竹筷的价值。有关废竹筷/聚合物复合材料的研究,尤其是在生物聚合物基质中利用提取的竹纤维的研究还很有限。在这项研究中,从竹丝水泥和竹子中提取的竹纤维被添加到一种名为聚丁二酸丁二醇酯(PBS)的生物聚合物中,添加量从 0 到 40wt%不等,以 10wt% 为增量。分析了由 WBC 纤维和 PBS 制成的复合材料的特性,并将其与直接从竹子中获取的竹纤维的 PBS 特性进行了比较。评估主要集中在形态、机械强度、热性能和流变特性等多个方面。结果表明,在 PBS 基体中引入 WBC 纤维与在 PBS 复合材料中使用竹纤维相比,并没有明显影响复合材料的性能或热稳定性。与在 PBS 中加入竹纤维的复合材料相比,WBC 纤维/PBS 复合材料的机械性能和流变性能略胜一筹。研究结果表明,从 WBC 中提取的竹纤维可有效增强生物聚合物复合材料。
