摘要
介绍了聚乳酸(PLA)加工流变性能的现状,描述了生物基塑料聚对苯二甲酸-己二酸丁二醇酯(PBAT)、聚己内酯(PCL),以及相关助剂对PLA流变性能的提升机理,具体涉及增塑剂、扩链剂、无机填料、纳米填料和淀粉对PLA流变行为的影响,并对PLA应用加工的发展前景进行了展望。
The present situation of processing rheological properties of polylactic acid(PLA)is introduced,and the mechanism of improving the rheological properties of PLA by bio based plastics such as poly(butylene terephthalate adipate)(PBAT),poly(caprolactone)(PCL)and related additives is described,specifically involving the effects of plasticizers,chain extenders,inorganic fillers,nano fillers and starch on the rheological properties of PLA.The development of PLA application and processing is prospected.
