摘　　要：淀粉由于来源广泛、价格低廉、可再生、可生物降解而被公认为最具发展前景的生物降解材料之一,但其力学性能易受环境湿度影响而降低,限制了其应用。将原淀粉/TPS进行物理或化学改性,或者与疏水性生物降解塑料共混是提高原淀粉/TPS耐水性的重要途径。主要综述了改善热塑性淀粉材料耐水性、提高力学性能的方法;另外,分别总结了国内外TPS/PLA、TPS/PCL和TPS/PBS共混材料研究进展及发展趋势。Due to widespread source, low price, renewability and biodegradability, starch has been widely con- sidered as one of the most potential biodegradable materials. However, the mechanical property of starch/TPS is quite sensitive to environment moisture, which limited its application. Starch/TPS should be physically/chemically modified or blended with hydrophobic polyesters in order to improve its water resistance. This review mainly summarizes some developments in chemical and physical modification of TPS to improve its waterproof and mechanical property. In ad- dition, review and development trend on TPS based biodegradable composites such as TPS/PLA,TPS/PCL and TPS/ PBS are also given.
