摘要

Biodegradable foams were prepared with poly(lactic acid) and starch by extrusion. The compression modulus of the foams was negatively related to the foam bulk density. The foam consists of both open- and close-cell structures. The presence of PLA significantly improved the water resistance of the foam, and significantly improved the foam recovery capacity, especially in high-moisture conditions.
