摘要
接枝共聚改性是提高聚乳酸性能的一种常用方法,能够扩展其使用范围。从共聚材料种类及性能的角度,分类介绍了近年来利用纤维素、淀粉、壳聚糖、葡聚糖等天然材料和亲水性、温敏性、聚氨基酸类聚合物等合成材料接枝改性聚乳酸的研究进展,分析了各类接枝改性聚乳酸材料的优缺点和应用,展望了该领域未来的发展方向和产业化应用中应该注意的问题,指出在今后聚乳酸基接枝共聚物材料的推广应用中应该关注产品的成本问题。
Graft copolymerization modification is one of the most effective methods to improve the performance of poly（lactic acid） and extend its applications. This paper attempts to review the recent progresses in the preparation of graft copolymers of poly（lactie acid） with natural materials, such as cellulose, starch, chitosan, dextram and so on, or synthesized polymers. The merits ＆ demerits and the applied direction of poly（lactic acid） based graft copolymers are expounded. And the future development direction is presented. Finally, it is pointed out that the cost issue should be paid particular attention to along with the rollout of the poly（lactic acid） based graft copolymers.
