摘要
生物降解高分子材料因医药、医学、环境等方面的需求而迅速发展起来,在近几十年,世界先进国家非常重视该领域的研究和开发工作,并取得一些重要进展。在简要介绍生物降解高分子材料的降解过程后,着重对全生物降解高分子材料的发展现状作了综述,其中包括化学合成高分子和天然高分子的研究和开发,同时对生物降解高分子材料存在的问题及其将来发展趋势等方面进行了讨论。
The biodegradable polymers,on account of demands in medicine,medical science and environment protection,develop very quickly in recent decades.The developed countries paid great attention to their research and development,some important achievements were made.After a brief introduction to the degradation mechanism of biodegradable polymers,this reviews the present status and development of degradable polymeric materials,including research and exploitation of synthetic and natural polymers.The present problems for the development of biodegradable polymers and their prospect and tendency are discussed.
