Abstract
Poly(vinyl chloride)/CaSO4 nanocomposites were prepared on Brabender plasticorder. Moreover, for comparison PVC/ commercial CaSO4 composites was prepared. The amount of loadings of nano CaSO4 and commercial CaSO4 was in the range of 0–12 wt%. Nano CaSO4 was synthesized by matrix-mediated growth technique. The size and shape of nano CaSO4 were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). These PVC nanocomposites were then subjected to mechanical, thermal analysis on UTM, and TGA respectively. Morphology studies of PVC nanocomposites were done on scanning electron microscope (SEM). The morphology study showed that nano CaSO4 get exfoliated and intercalated with the PVC matrix. Notched Charpy impact strengths of PVC nanocomposites was drastically improved compared to that of pristine PVC and commercial CaSO4 composites. PVC/CaSO4 nanocomposites showed higher values of tensile strength, elongation at break and impact strength than PVC/CaSO4 (commercial) composites. Impact strengths also gives some drastic dependence on nano CaSO4 content and give a maximum value at certain CaSO4 loadings.
