【摘要】 将纳米CaCO3 进行表面改性 ,制备了纳米CaCO3 PVC复合材料。用透射电子显微镜观察纳米CaCO3 改性前后及纳米CaCO3 PVC复合材料的微观结构。结果表明 ,表面改性后纳米CaCO3 在PVC基体中达到了纳米级的分散 ,对PVC复合材料有显著的增韧作用 ,复合材料的缺口冲击强度达到 41 2kJ/m2 。此外 ,还研究了纳米Ca CO3 PVC的流变性能

【Abstract】 Nanocomposites of surface modified Nano CaCO 3 of average size 30~50 nm and PVC were prepared. The microstructure of dispersed calcium carbonate nanoparticles in the nanocomposites was observed by the aid of electronic microscope. The results showed that CaCO 3 nanoparticles were well dispersed in PVC matrix. Remarkable improvement of toughness of PVC composites was observed. The impact strength of the PVC nanocomposite reached 41 2 kJ/m 2. The rheological property of Nano CaCO 3 PVC composites was also investigated.
