聚乳酸在剪切作用下的结晶行为研究进展
Research Progress in Crystallization of Polylactide Under Shear Effects
摘要
Abstract
This paper reviewed the studies on the effects of shear on crystallization kinetics,crystal morphology and crystal structure of polylactide (PLA ).These studies indicated that the crystallization kinetics of PLA was improved remarkably by shearing effect,for example,the crystallization induce time was reduced and the nuclei growth rate was improved,thus leading to an increase in crystallinity of PLA.Moreover,the point-like,row-like and even shisi-like crystals could be formed for PLA under shear.This suggests that the crystalline morphology of PLA can be improved under shear.The shear effect can also result in a phase transition fromα′-form crystals to the α-form one and,therefore,makes the crystal structure more perfect.关键词
