Abstract

This research investigates the production of biodegradable films using a combination of gum odina (GO) and polyvinyl alcohol (PVA) with varied ratio. The study focuses on the chemical, physical, and mechanical properties of PVA-GO composite films, emphasizing how versatile and biodegradable they may be for a range of packaging applications. Solvent-cast PVA-GO films with different ratios are subjected to a methodical analytical process to determine several parameters like mechanical qualities, thermal stability, biodegradability in soil, contact angle, transparency, water vapor permeability, moisture content, thickness, density, water solubility, microstructure, and FTIR analysis. The outcomes demonstrate that GO improves UV barrier qualities and water vapor permeability. Additionally, the films showed notable biodegradability, acceptable thermal stability, and mechanical qualities. In short, PVA-GO films can provide an eco-friendly packing substitute with adaptable qualities fit for a range of uses. Therefore, this research may further contribute promising information in the field of biodegradable packaging materials in the future.

不同比例的聚乙烯醇-奥迪纳胶对制备可生物降解复合膜及其特性的影响

本研究调查了使用不同比例的奥迪纳胶（GO）和聚乙烯醇（PVA）组合生产可生物降解薄膜的情况。研究重点是 PVA-GO 复合薄膜的化学、物理和机械性能，强调它们在一系列包装应用中的多功能性和生物降解性。对不同比例的溶剂浇铸 PVA-GO 薄膜进行了有条不紊的分析过程，以确定多个参数，如机械质量、热稳定性、在土壤中的生物降解性、接触角、透明度、水蒸气渗透性、含水量、厚度、密度、水溶性、微观结构和傅立叶变换红外分析。结果表明，GO 提高了紫外线阻隔性和水蒸气渗透性。此外，薄膜还具有显著的生物降解性、可接受的热稳定性和机械性能。简而言之，PVA-GO 薄膜可以提供一种环保型包装替代品，其质量适应性强，用途广泛。因此，这项研究未来可能会在可生物降解包装材料领域提供更多有前景的信息。
