聚乳酸( Poly lactic acid,简称为PLA)是一种非石油基可生物降解的环境友好型材料,具备一定的机械强度与物理性能,被广泛应用于包装、生物医药以及纺织工业等领域。 PLA是结晶性聚合物,在加工过程中会出现结晶现象,可以通过控制结构条件、成型条件以及选择结晶成核剂,控制其结晶速率,改善PLA的宏观性能。由于PLA具有较好的材料性能并且对环境零污染,现在被广泛应用于各个领域,具有广阔的发展前景。
Research Progress on Poly Lactic Acid (PLA) Crystallization Factors
Poly lactic acid ( PLA) is a non-petroleum-based biodegradable environment-friendly material, with certain mechanical strength and physical properties, is widely used in packaging, bio-pharmaceutical and textile industry and other fields. PLA is a crystalline polymer, and it can crystallize in the process, which can be controlled in crystallization rate by structural conditions, molding conditions, and nucleating agents, to improve its macroeconomic performance. Since PLA has better material properties and does not pollute the environment, it is now widely used in various fields, and has broad prospects in the future.
