摘　　要：本文回顾了淀粉填充塑料的发展历史和国内外研究和开发现状，讨论了其制备、加工、应用及降解性能。在分析结构－性能关系的基础上，指出制备淀粉填充塑料的关键在于提高淀粉与基体树脂的相容性和控制淀粉分散相形态，以及引入适当的光降解机理从而赋予材料可预测的使用寿命和彻底的降解特性。The history and developments in starch-filled plastics were reviewed according to the dependence of properties on structure and morphology.In preparation of starch-filled plastics,cautions should be taken to improve the interfacial compatability between starch and synthetic resin matrix,to lower the size of starch filler and to control its destructured level.The degradability of starch-filled plastics and its assessment were also discussed based on its degradation mechanism,i.e.,a therm-oxidative or photo-oxidative degradation of the synthetic matrix accelerated by starch biodegradation.
