This research experimentally synthesizes bamboo fiber‐reinforced biocomposites by using bamboo fiber (BF) as filler material and poly(butylene succinate) (PBS) as biodegradable polymer matrix. The experimental filler materials included alkaline‐treated BF and untreated BF. The alkali treatment of BF was carried out to remove the hydrophobic components from the BF surface. The PBS/BF ratios were varied between 90/10, 80/20, and 70/30 (w/w). The experiments revealed that the tensile strength of PBS/treated BF biocomposites were higher than that of PBS/untreated BF ones, independent of BF content. Elongation at break decreased with increase in BF content, while Young's modulus increased as BF content increased. The Izod impact strength of the biocomposites were similar to that of neat PBS. The water absorption capacity of PBS/BF biocomposites increased with increase in BF content. The water uptake of alkali‐treated BF was higher than that of untreated BF as lignin and hemicellulose were removed from the BF surface. The novelty of this research lies in the use of biodegradable PBS polymer as biocomposite matrix reinforced with natural fiber, as opposed to conventional petroleum‐based non‐biodegradable polymers. Moreover, this research also performed water absorption experiments to characterize the effect of alkali treatment on bamboo fibers. The characteristic of biocomposites is appropriate to be used as packaging and indoor furniture parts.

环保竹纤维增强聚丁二酸丁二醇酯生物复合材料

这项研究以竹纤维（BF）为填充材料，聚丁二酸丁二酯（PBS）为可生物降解的聚合物基质，通过实验合成了竹纤维增强的生物复合材料。实验性填料包括碱处理过的高炉和未处理过的高炉。进行BF的碱处理以从BF表面去除疏水性组分。PBS / BF比在90 / 10、80 / 20和70/30（w / w）之间变化。实验表明，PBS /处理过的高炉生物复合材料的拉伸强度高于PBS /未处理过的高炉生物复合材料的拉伸强度，而与BF含量无关。断裂伸长率随BF含量的增加而降低，而杨氏模量随BF含量的增加而增加。生物复合材料的悬臂梁式冲击强度与纯PBS相似。PBS / BF生物复合材料的吸水能力随BF含量的增加而增加。碱处理过的BF的吸水率高于未处理过的BF，因为从BF表面去除了木质素和半纤维素。这项研究的新颖性在于使用可生物降解的PBS聚合物作为天然纤维增强的生物复合基质，这与传统的石油基不可生物降解的聚合物相反。此外，该研究还进行了吸水实验，以表征碱处理对竹纤维的影响。生物复合材料的特性适合用作包装和室内家具零件。这项研究的新颖性在于使用可生物降解的PBS聚合物作为天然纤维增强的生物复合基质，这与传统的石油基不可生物降解的聚合物相反。此外，该研究还进行了吸水实验，以表征碱处理对竹纤维的影响。生物复合材料的特性适合用作包装和室内家具零件。这项研究的新颖性在于使用可生物降解的PBS聚合物作为天然纤维增强的生物复合基质，这与传统的石油基不可生物降解的聚合物相反。此外，该研究还进行了吸水实验，以表征碱处理对竹纤维的影响。生物复合材料的特性适合用作包装和室内家具零件。
