The main goal of this work is to modify surface of nano CaCO3 with silica by an elegant approach of sol–gel method and also to compare the influence of sol–gel modified nano CaCO3 with unmodified nano CaCO3 in the cure, mechanical and thermal properties of acrylonitrile butadiene rubber (NBR) nanocomposites. The surface modification of nano CaCO3 is characterized by Fourier transform infrared spectra...
