摘　　要：综述了近几年国内外改性聚乳酸(PLA)发泡技术的研究进展,针对PLA在发泡方面熔体强度和结晶性能的不足,介绍了通过加入扩链剂、交联剂、成核剂、纤维和其他聚合物等物质来改善PLA发泡性能的方法、效果和机理;最后,对改性聚乳酸发泡技术的未来发展进行了展望。This paper introduced the research progress in the modified poly(lactic acid)(PLA)foaming technology at home and abroad in recent years.In view of the insufficient melt strength and crystalline properties of PLA in foaming,the paper also discussed the methods,effects and mechanism for improving the foaming properties of PLA through the addition of various additives such as chain extenders,crosslinkers,nucleating agents,fibers and other polymers.Finally,the future development of modified PLA foaming technology was prospected.
