摘要：
Polylactic acid (PLA) is a new type of environmentally and friendly plastic with good performance, and its expanded beads not only have the advantages of wide source, complete degradability of PLA raw materials, excellent comprehensive mechanical properties, but also show high performance through its microcellular foam structure. Advanced application standards require reduced material usage, energy savings, environmental-friendly and many other benefits. In this paper, the foaming properties, cell regulation, crystallization control and process conditions of polylactic acid beads at home and abroad were reviewed. The composite modification methods of polylactic acid completely and incompletely degradable systems were summed up and finished. The existing problems have been put forward, the advantages and disadvantages of different process conditions were compared. The future research on polylactic acid bead foaming technology was prospected. © 2020, Editorial Board of Polymer Materials Science & Engineering. All right reserved.
