摘要

聚乳酸（PLLA）因具有优异的可生物降解性、生物相容性、较高的机械强度和易加工性能，被认为是目前最具有工业化应用前景的绿色生物基高分子材料。但是聚乳酸材料的韧性差、结晶速率低和耐热性差等缺点限制了它在包装、电子、电器、3D打印等领域的广泛发展与应用。本文综述了国内外在提高聚乳酸耐热性能方面的研究进展，主要是通过添加成核剂、制备立构复合体（SC-PLA)、纳米增强聚乳酸复合材料和与高耐热性高分子材料共混等技术提高聚乳酸的耐热性，从而扩展聚乳酸在工程领域的应用。

Abstract

Poly(L-lactic acid) (PLLA) is regarded as one of the most promising green bio-based polymer materials in industrial application

because of its excellent biodegradability

biocompatibility

high mechanical strength and easy processing performance. However Poly(L-lactic acid) (PLLA) exhibits poor toughness

low crystallization rate and poor heat resistance

these inherent drawbacks limit its development and application in engineering

electronics

electrical and automotive engineering

and 3D printing. Progress in improving the heat resistance of poly(L-lactic acid) are reviewed in this article. The heat resistance of PLLA were enhanced through several methods

such as adding nucleating agents

preparing stereo-complex microcrystal complexes

and blending with nano-particles and high heat resistance polymer materials

which enlarged its application in engineering fields.
