【摘要】 聚乳酸类材料是一种用途广泛的可生物降解材料,聚乳酸通过改性,其相应的性能会得到很大的改善,其应用领域更加广阔。文章对聚乳酸的改性研究进展进行了综述,聚乳酸的改性方法有物理改性(包括共混改性和增塑改性等)、化学改性(包括共聚改性和交联改性等)和复合改性等。更多还原

【Abstract】 Polylactic acid (PLA) is a widely used biodegradable polymer, while it is modified, the corresponding performance of PLA would be greatly improved, so its applications will be more broaden. The methods of modifications of PLA were reviewed, the methods include physical modification (which was divided into blending modification, plasticized modification and so on), chemical modification (which was divided into copolymerization modification and cross-linked modification.) and composite modification.更多还原
