Morphology and Biodegradability Study of Natural Latex-Modified Polyester–Banana Fiber Composites

ABSTRACT

Composites of banana fiber were prepared using polyester resin/natural latex (Euphorbia coagulum) blend as matrix and evaluated for various physicomechanical properties. The best physicomechanical properties have been obtained by replacing 40% of polyester resin with coagulum. The morphology and biodegradability of the controlled and optimum composition of the composite, i.e., composite containing banana fiber, Euphorbia coagulum, and polyester resin in the ratio 40: 24: 36, were carried out. Morphology study shows that incorporation of Euphorbia coagulum in polyester–banana fiber composites improves the compatibility between the fiber and matrix. Biodegradability study shows that the composite containing polyester resin/Euphorbia coagulum blend as matrix exhibited a high degree of biodegradation compared to the composite containing polyester resin as the matrix. The use of developed green composites may help in reducing the generation of nonbiodegradable polymeric wastes.

摘要

香蕉纤维的复合材料是使用聚酯树脂/天然乳胶(欧波比亚胶)混合作为基质制备的,并评估各种物理力学特性. 通过将 40% 的聚酯树脂替换为胶质树脂,获得了最佳的物理力学性能. 进行了复合物的受控和最佳组合物的形态和生物降解性,即含有香蕉纤维、欧波比亚胶和聚酯树脂的复合物,比例为40:24:36. 形态学研究表明,在聚酯和香蕉纤维复合材料中加入Euphorbia coagulum可改善纤维和基质的相容性. 生物降解性研究表明,与聚酯树脂为基质的复合物相比,含有聚酯树脂/欧波比亚凝血混合的复合材料表现出高度的生物降解性. 使用开发的绿色复合材料有助于减少不可生物降解的聚合物废物的产生.
