Study on Characteristics of Environmental-friendly and Biodegradable Material Polylactic Acid

Abstract

Abstract: Polylactic acid (PLA) is a kind of important degradable material, which is being increasingly used as biomaterials, thus it attracted much attention. In this paper, the physical and mechanical performances, chemical and biodegradable properties of PLA are discussed briefly. Two main synthesis methods of PLA, condensation polymerization of lactic acid and ring-opening polymerization of lactide in recent years are described in details, and the situation of production is analyzed as well. Finally, the fields of synthesis, application, current state of development and the prospects of PLA are presented. Some suggestions on its industrialization are given, once the manufacture of PLA is industrialized, it can be of wide application in the fields of medicine and degraded plastics.
