摘要：
PVC/nano CaCO3 composites were prepared on Brabender Plasticorder. For comparison purposes, commercial CaCO3 composites were also prepared. Characterization of the nano CaCO3 and nanocomposites were done using scanning electron microscope (SEM) and transmission electron microscope (TEM). Their mechanical and thermal properties were also studied. Exfoliation was observed with the addition of different sizes of nano CaCO3 filled in PVC composites. Best properties were observed with 9nm CaCO3 PVC composites. Tensile strength and modulus improved significantly even though the amount of addition of nano filler is low. Thermal properties of PVC/nanocomposites were found to be better compared to that of commercial filled CaCO3 in PVC composites.
