Rubber silica nanocomposites are prepared by mixing nitrile rubber (NBR) with surface modified silica nano particles. Silica nano particles are synthesized by sol-gel method that involves hydrolysis followed by condensation of tetraethyl orthosilicate (TEOS). Surface modification of silica particles is done with the treatment of silane coupling agent viz. 3-mercaptopropyltrimethoxysilane. Presence of silane coupling agent in silica is revealed by IR studies. Thermogravimetric analysis is done to find out silica content in the composites and to study the thermal properties. Stress strain studies are found to be useful to assess the improvement of the mechanical properties of the composites.
