Abstract: 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.
