The effect of TiO2 and CaCo3 nano particles on mechanical and thermal properties of PVC/ABS blend

The effects of nanoscale calcium carbonate (nano-CaCO3) and titanium dioxide (nano-TiO2) particles at different content ( 1, 2 wt%) on the mechanical and thermal properties of of poly(vinyl chloride) (PVC)/ acrylonitrile– butadiene–styrene terpolymer (ABS) blend were investigated. The nanocomposites were characterized by impact followed by scanning electron microscopy of the fracture surfaces. Results indicate an enhancement in mechanical properties of PVC/ABS nanocomposite after addition of TiO2 and CaCO3 nanoparticles. The maximum impact strength were found at TiO2 and CaCo3 fraction of 2 wt.% only. The impact strength of the PVC/ABS nanocomposite was not improved by further addition of the filler. . The scanning electron microscopy result shows that nanoparticles making void and improved impact strength
