Abstract:

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.

Key words: poly(lactic acid), modification, foaming, property
