摘　　要：淀粉是一种天然多糖,具有价廉、易得和可降解的优点,但其较强的亲水性导致淀粉膜的机械性能较差,需要与一些高分子材料进行共混改性。传统高分子材料与淀粉的相容性较差,需要添加相容剂增加两者的相容性与界面强度。该文主要介绍了反应性相容剂和非反应性相容剂的种类和性质,以及两类相容剂对淀粉复合膜微观结构、热稳定性、机械性能和阻隔性能的影响,对淀粉基薄膜生产过程中选择合适的相容剂具有指导作用。Starch is a natural polysaccharide with the advantages of low price,easy availability and degradability,but its strong hydrophilicity leads to poor mechanical properties of the starch film,and therefore,it requires blending and modification with some polymer materials.Traditional polymer materials have poor compatibility with starch,and compatibilizers need to be added to increase their compatibility and interface strength.This article mainly introduced reactive compatibilizers and non-reactive compatibilizers,and the effects of two types of compatibilizers on the microstructure,thermal stability,mechanical properties and barrier properties of starch composite films.This article has a positive effect on the selection of suitable compatibilizers in the production of starch-based films.
