摘　　要：介绍可降解塑料的分类以及每种可降解塑料的基本降解原理。综述常见的三种可降解塑料:生物降解塑料、光降解塑料以及光-生物降解塑料在国内外的研究进展。介绍化学合成型、共混型、天然型以及微生物合成型等生物降解塑料。探讨添加型光降解塑料和共聚型光降解塑料。分析既可以进行生物降解又可以进行光降解的光-生物降解塑料。探讨当前可降解塑料存在的一些问题如可控较差、成本较高、种类有限等,并对可降解塑料的未来发展趋势进行展望。The classification of degradable plastics and the basic degradation principle of each type of degradable plastics were introduced. The research progress of three common degradable plastics: biodegradable plastics, photodegradable plastics and photo-biodegradable plastics at home and abroad in recent years was reviewed. Chemical synthetic, blending,natural and microbial synthetic biodegradable plastics were introduced. Additive photodegradable plastics and copolymer photodegradable plastics were discussed. The photo-biodegradable plastics which can be both biodegradable and photodegradable were introduced. The existing problems of degradable plastics such as poor controllability, high cost and limited types were discussed, and the future development trend of degradable plastics was prospected.
