摘要
本文在参考二十八篇文献及专利报道的基础上详述了以多糖类天然高分子为原料的生物降解材料的研究发展。淀粉、纤维素、壳聚糖及其它多糖,是自然界中大量存在的天然高分子材料,来源丰富,价格低廉,且易被微生物分解。多糖类降解材料可用通用的加工方法和设备加工成型,产品性能优良,可完全生物降解,其开发和应用是解决目前世界范围内的塑料产生的污染问题的理想途径。
Basing on 28 literatures and patent reports describes the development ofbiodegradable materials produced from native polysaccharides.Starch,cellulose,chitosan and other polysaccharides are native polymers hem*g plenty in nature,which are rich in resources, low cost and easy to be decomposed by bacteria.Polysaccharide-based biodegradable materials can be processed by commonlyused techniques. The products have excellent properties and are biodegradablecompletely. Developing and using polysaccharide-based materials may be a rightway to solve the environmental pollution from plastics all over the world.
