聚乳酸是以玉米等可再生资源为原料生产的生物降解塑料,近年备受关注。但是与普通塑料相比,聚乳酸系生物降解塑料耐热性、抗冲击性及耐久性差,因此其使用范围受到限制。日本Unitika公司2000年开始,通过纳米级分子改质生产纳米复合材料,提高聚乳酸塑料的耐热性和耐久性,其用途几
Polylactic acid is a biodegradable plastic produced from renewable resources such as corn and has drawn much attention in recent years. However, compared with ordinary plastic, polylactic acid based biodegradable plastic heat resistance, impact resistance and durability is poor, so its use is limited. Japan Unitika company started in 2000, through the nanoscale molecular modification of nanocomposites to improve the heat resistance and durability of polylactic acid plastics, and its use of a few
