Abstract

In recent years, researchers and industries have made efforts to decrease the reliance on fossil fuel-based materials due to the rise in environmental consciousness. A potential environmentally friendly alternative to petroleum-based, non-biodegradable polymeric materials is known to be natural fiber-reinforced polymer composites. Polyvinyl alcohol (PVA) is a biodegradable synthetic polymer that is water-soluble, easy to use, having film-formation property and good potential as a biodegradable matrix in environmentally friendly composites. The objective of this work has been to create a versatile, lightweight, flexible bio-composite based on nonwoven viscose fabric using PVA and a crosslinking agent (glutaraldehyde), and to analyze the effects of the crosslinking agent and of the nonwoven viscose filler in the PVA matrix on the mechanical and UV properties of the composite. The structural, chemical and mechanical properties of the composite were investigated using FTIR, and tensile and UV testing. The results showed that the composite exhibited high tensile strength, but with a drop in elongation. FTIR verified the interaction of the two polymers in the composites. The flexible bio-composite can be potentially used for food packaging applications.

戊二醛交联剂对粘胶非织造布-聚乙烯醇柔性复合材料性能的影响

近年来，由于环保意识的增强，研究人员和工业界都在努力减少对化石燃料材料的依赖。天然纤维增强聚合物复合材料是石油基、不可生物降解聚合物材料的潜在环保替代品。聚乙烯醇(PVA)是一种生物可降解的合成聚合物，具有水溶性、易使用、成膜性好等特点，在环境友好型复合材料中具有良好的生物降解基质潜力。本工作的目的是利用PVA和交联剂(戊二醛)在非织造粘胶织物的基础上创造一种多功能、轻质、柔性的生物复合材料，并分析交联剂和PVA基体中非织造粘胶填料对复合材料力学性能和紫外线性能的影响。利用红外光谱、拉伸和紫外测试对复合材料的结构、化学和力学性能进行了研究。结果表明，该复合材料具有较高的抗拉强度，但伸长率下降。FTIR验证了复合材料中两种聚合物的相互作用。柔性生物复合材料可以潜在地用于食品包装应用。
