木薯淀粉基膜材料的研究进展

木薯淀粉具有较好的延展性、黏度、渗透力等优点，利用木薯淀粉的可降解性、成膜性等特点生产可降解的天然聚合物膜材料具有较好的可行性。目前，木薯淀粉基膜材料的相关研究主要集中在生物可降解膜、抗菌膜、pH值指示膜、缓释膜等领域。而木薯淀粉基膜材料的热稳定性与机械性能较传统热塑性材料差，所以探究强化改性及工艺技术将是研究重点。本文综述了木薯淀粉基膜材料的制备方法、强化改性及应用，并展望未来发展趋势。

Progress in Research on Cassava Starch-Based Film Materials

Cassava starch has the advantages of good ductility, viscosity and permeability, and is feasible to be used in the production of degradable natural polymer film materials due to its good degradability and film-forming capacity. Most current studies on cassava starch-based film materials are focused on the fields of biodegradable film, antibacterial film, pH indicator film and slow-releasing film. However, cassava starch-based film materials have worse thermal stability and mechanical properties than conventional thermoplastic materials. Hence, modification of cassava starch-based film materials will be the focus of future studies. This paper summarizes the methods commonly used for preparing, strengthening and modifying cassava starch-based film materials and reviews the application of cassava starch-based film materials. Meanwhile, an outlook on future trends is presented.
