Abstract

Poly (lactic acid) is biodegradable and green polymer material.The basic properties of poly (lactic acid) and the recent research progress on the preparation of poly (lactic acid) membranes were reviewed,including thermally induced phase separation,immersion precipitation phase conversion,electrostatic spinning,etc.Due to its inherent brittleness seriously hindered its application in membranes,introduced systematically chemical and physical modifications to toughen the poly (lactic acid) membranes.Finally,the research direction and emphases of toughening modification of PLA membranes were pointed out.
