| Abstract: | Based on the introduction of the biologic, physical and mechanical properties of biomaterials poly(lactic acid), some advances in researches of plasticization, copolymerization, blend and composite of poly(lactic acid) were reviewed. After these processing methods, the properties of mechanism, hydrophile and functionality may be improved, and the biodegradable property can be reserved. Hence, poly (lactic acid) can be applied in the biomedical and environmental areas perfectly. |
