摘　　要：采用碳酸化工艺,合成了一系列具有不同晶体规整度的纳米碳酸钙(nano-CaCO_(3)),研究了其晶体规整度对聚对苯二甲酸乙二醇酯(PET)复合材料结晶性能、流变性能和力学性能的影响。结果表明:nano-CaCO_(3)的晶体规整度越高,PET复合材料的剪切变稀性能越好,越有利于PET成核结晶,使其力学性能更好。A series of nano calcium carbonate(nano-CaCO_(3))with different crystal regularity were synthesized using carbonation process.Effects of nano-CaCO_(3) crystal regularity on the crystallization property,rheological property and mechanical property of polyethylene terephthalate(PET)composite were studied.The results show that the higher the crystal regularity of nano-CaCO_(3),the better the shear thinning performance of PET composite,which is more conducive to PET nucleation and crystallization and leads to better mechanical properties.
