Combined crystallization kinetics analysis obtained via rheometry and morphological observation of crystals growth performed on POM, two different mechanisms of shear-enhanced crystallization for PP/ grafted MWCNTs composites were suggested:(1) at low temperature, strong heterogeneous nucleation plays a dominant role on the. crystallization behavior, which would be saturated at a higher filler content, and the effect of shear-enhanced crystallization was weak;(2) at high temperature, the effect of heterogeneous nucleation was substantially depressed, and the crystallization of the composite was obviously accelerated by pre-shear and the thread-like crystallites were generated earlier than the spherulites.

结合流变测试结果和热台偏光显微镜观察的结晶形貌发展过程，对于PP／G—MWCNTs体系得到了两个不同的剪切影响机理：(1)在低温条件下，强烈的异相成核作用对结晶行为的影响占主导优势，而剪切作用对结晶的影响十分微弱，同时，在填料含量较高是，异相成核作用具有饱和性；(2)在高温条件下，异相成核作用被抑制，复合体系的结晶主要受到预剪切作用的影响，并且纤维状晶体较球晶更易生成。
