摘　　要：随着人们对环境问题的日益关注,研究和开发生物相容性好、对人体和环境友好的生物可降解聚乳酸基驻极体材料已成为当前热门课题之一。本研究在现有高分子驻极体制备原理和方法的基础上,总结了生物可降解左旋聚乳酸在结构、组成和电学性能等方面具备的驻极体基本性能特征,根据早前的研究,分析了制备结晶型聚乳酸基驻极体薄膜材料时添加极性较强的成核剂的必要性,提出在制备这类驻极体薄膜材料时必须考虑聚乳酸的结晶和玻璃化转变对其性能和工艺的影响。本研究为在我国开发聚乳酸基驻极体薄膜材料提供了理论参考。With the increasing concern on environmental problems, it has become one of the hottest topics to study and develop the bio - degradable, eco - friendly ploylactic acid based electret material. In this paper, the structure, component and electrical properties of Poly （ L - lactide） - based electret material were introduced based on prepared principle and method of electret. According to previous researches, it was necessary to introduce crystallinity nucleator with strong polarity to prepare Poly （ L - lactide） （PLLA）. And effect of crystallinity and glass transition temperature on electrical characteristics of PLLA was analyzed in the prepared process. This study provides a theoretical reference for preparing Poly （ L - lactide） - based electret film material in China.
