Bio-composites containing kenaf and starch as the filler and matrix, respectively, and Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) as plasticizers were fabricated. The acetylation of hydrophilic kenaf increased the hydrophobic matrix and surfactant bonding in the complex, and the starch matrix increased the biodegradability. The physical, thermal, and biodegradability properties of composites comprising acetylated kenaf and starch (S), acetylated kenaf, starch, and PVA (S+PVA), and acetylated kenaf, starch, and PEG (S+PEG) were evaluated. The results showed that the acetylation of kenaf caused its surface to swell, improving the interfacial adhesion between kenaf and starch in the composites, whereas PVA and PEG did not enhance the physical properties of the composites. The addition of plasticizers caused a slight improvement in the thermal fluidity and stability of the acetylated kenaf composites. In addition, the composites buried in soil showed higher biodegradability than those buried in compost. The presence of moisture in the soil also increased the biodegradability by 80 %. The results of this study demonstrate the high potential of the acetylated kenaf composites as an alternative to synthetic polymer products. Moreover, considering their biodegradable nature, these composites can be applied in treatments and techniques that are focused on the safe disposal of plastic waste for the mitigation of environmental pollution.

制备了分别含有洋麻和淀粉作为填料和基质，聚乙烯醇（PVA）和聚乙二醇（PEG）作为增塑剂的生物复合材料。亲水性洋麻的乙酰化增加了复合物中疏水基质和表面活性剂的结合，淀粉基质增加了生物降解性。评估了包含乙酰化洋麻和淀粉 (S)、乙酰化洋麻、淀粉和 PVA (S+PVA) 以及乙酰化洋麻、淀粉和 PEG (S+PEG) 的复合材料的物理、热和生物降解性能。结果表明，洋麻的乙酰化导致其表面膨胀，提高了复合材料中洋麻和淀粉之间的界面粘合力，而 PVA 和 PEG 并未增强复合材料的物理性能。增塑剂的加入使乙酰化洋麻复合材料的热流动性和稳定性略有改善。此外，埋在土壤中的复合材料比埋在堆肥中的复合材料显示出更高的生物降解性。土壤中水分的存在也将生物降解性提高了 80%。这项研究的结果证明了乙酰化洋麻复合材料作为合成聚合物产品的替代品的巨大潜力。此外，考虑到其可生物降解的性质，这些复合材料可应用于专注于塑料废物安全处置以减轻环境污染的处理和技术。土壤中水分的存在也将生物降解性提高了 80%。这项研究的结果证明了乙酰化洋麻复合材料作为合成聚合物产品的替代品的巨大潜力。此外，考虑到其可生物降解的性质，这些复合材料可应用于专注于塑料废物安全处置以减轻环境污染的处理和技术。土壤中水分的存在也将生物降解性提高了 80%。这项研究的结果证明了乙酰化洋麻复合材料作为合成聚合物产品的替代品的巨大潜力。此外，考虑到其可生物降解的性质，这些复合材料可应用于专注于塑料废物安全处置以减轻环境污染的处理和技术。
