This paper focuses on the effect of okra bast fillers on biodegradation of poly(vinyl alcohol) composites. Fibers were obtained from okra plant stems via biological degumming and subjected to different chemical treatments such as scouring, alkalizing, maleic anhydride treatment, and vinyl acetate grafting. The fibers were ground and PVA-okra bast filler composites were produced at 20 wt% fiber load via the solution casting method. The obtained composites were tested in terms of mechanical properties and exposed to biodegradation in soil. Effects of okra bast filler addition and chemical treatments on changes in mass, breaking strength, elasticity modulus, and breaking elongation of composites upon soil biodegradation were determined. The composites can be considered for utilization in packaging and agricultural applications.
本文聚焦于秋葵韧皮纤维填料对聚（乙烯醇）复合材料生物降解的影响。通过生物脱胶从秋葵植物茎中获取纤维，并对其进行不同的化学处理，如精练、碱化、马来酸酐处理和醋酸乙烯酯接枝。将纤维研磨后，通过溶液浇铸法在纤维负载量为20 wt%的情况下制备了PVA-秋葵韧皮纤维填料复合材料。对所得复合材料进行了力学性能测试，并使其在土壤中进行生物降解。确定了添加秋葵韧皮纤维填料和化学处理对复合材料在土壤生物降解过程中质量、断裂强度、弹性模量和断裂伸长率变化的影响。该复合材料可考虑用于包装和农业应用。
