摘　　要：介绍了可完全生物降解塑料的降解过程及种类,尤其是目前最具有市场前景的3类可完全生物降解塑料:微生物合成降解塑料(PHA、PHB)、化学合成降解塑料(PCL、PBS、PLA)、天然高分子共混降解塑料的研究进展。通过研究完全生物降解塑料在医学、力学、膜材料等实际上的应用及改性后的提高可知,完全生物降解塑料显示出比传统塑料更加广阔的应用前景,并能够解决当今社会上面临的一系列生态、资源等问题。完全生物降解塑料作为一种新型的"绿色塑料",正逐步取代传统塑料走到人们的生活实践中。The paper introduced the process and types of completely biodegradable plastics, especially the research development of microbialsynthesis degradable plastics （PHA and PHB）, chemical synthesis degradable plastics （PCL, PBS and PLA） and natural polymer blending degradable plastics which have the greatest market prospect. After numerous researches on its practical application in the medical science, me- chanics and membrane materials, the completely biodegradable plastic shows wider application prospect than the traditional plastics. What＇ s more, it can help solve a series of environmental and resources problems which the whole society are confronted with. As a novel ＂green plas- tics＂, completely biodegradable plastics is taking the place of traditional plastics to be widely used in practical life.
