摘　　要：聚乳酸(PLA)因其优异的可降解性、相容性、易加工性,并且机械强度高、无毒、无刺激性,目前被公认为是一类最具工业化应用前景以及研究最为广泛的绿色生物基可降解高分子材料。但是PLA结晶速率慢、结晶度低、耐热性差的缺点严重限制了其在对温度要求较高领域的推广与应用。本文主要从晶型改性、共混改性及交联改性等方面综述了当前国内外PLA耐热性研究的新进展,并对高耐热性PLA的未来发展进行了展望。Polylactic acid(PLA)is a kind of the most widely studied green biodegradable polymer material and is currently recognized as the most promising industrial application due to its excellent biodegradability,biocompatibility,processability,high mechanical strength,non-toxicity,and no stimulation.However,the disadvantages of slow crystallization rate,low crystallinity,and poor heat resistance of PLA severely limit its application in the fields with higher temperature requirements.This paper reviewed the current research on the heat resistance of PLA inside and outside China,mainly from the crystal type modification,blending modification,and cross-linking modification,and then prospected the future development of high heat resistance PLA.
