Poly (lactic acid) (PLA) is a polymer synthesized from lactic acid with good biocompatibility and biodegradability. At present, PLA manufactured on industrial scale is mainly synthesized from L-lactic acid. The obtained products have good transparency but poor heat resistance. Adding nucleating agents could increase the crystallinity of PLA, to improve heat resistance. We reviewed the progress of research on organic and inorganic nucleating agents that can be used for PLA synthesis.
聚乳酸（PLA）是一种由乳酸合成的聚合物，具有良好的生物相容性和生物降解性。目前，工业规模生产的PLA主要由L-乳酸合成。所得产品具有良好的透明度，但耐热性较差。添加成核剂可以提高PLA的结晶度，从而提高耐热性。我们综述了可用于PLA合成的有机和成核剂的研究进展。
