Plasticization and Toughening Modification of Poly(lactic acid) as Biodegradable Plastics


 

Poly(lactic acid) is a biodegradable polyester from renewable resources with a glass transition temperature at about 60°C and becomes a promising material for its high strength, modulus, and excellent transparency. Except for its well-known medical applications, its usage as a commodity plastic with high productivity is approaching. The plasticization and toughening modification of poly(lactic acid) is carried out to meet the need of its usage in plastics with varied hardness and impact strength. Poly(butylene succinate)-grafted cellulose nanocrystal and dicumyl peroxide exhibit great effects on the mechanical properties of poly(lactic acid).
