| Abstract: | Nanocomposites of surface2modified Nano-CaCO3 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 CaCO3 nanoparticles were well-dispersed in PVC matrix. Remarkable improvement of toughness of PVC composites was observed. The impact st rength of the PVC nanocomposite reached 41.2 kJ / m2 . The rheological property of Nano-CaCO3-PVC composites was also investigated. |
