Abstract

<p>The high temperature resistant Polymer-nanographite composite was prepared using Nanographite as reinforcing fillers in Acrylonitrile Butadiene Rubber (NBR) and investigated. The effect of increasing nanographite loadings on mechanical properties like tensile strength, modulus and Elongation at break was studied. Mechanical tests demonstrate that the NBR/graphite nanocomposites possess greatly increased elastic modulus and tensile strength, and desirably strong interfaces. The NBR nanocomposites showed higher thermal stability in comparison unfilled rubber vulcanizate. Physico-mechanical properties of the polymer nanocomposites after air ageing studies at 200°C showed improved thermal resistance and increases with loading of nanographite. The dispersion of the nanographite filler in the Nitrile Rubber was achieved using liquid NBR polymer matrix and was investigated by SAXD, SEM and Mechanical properties. SAXD study indicated that the composites did not change the inter-gallery distance (d-spacing) of the graphite platelets and as the loading of nano filler increases the dispersion of nanoparticles improved due to filling effect.</p>
