摘要

Ternary nanocomposites based on nanograpite platelets, OMMT and polyurethane were prepared using in-situ polymerization with the aim of achieving low percolation threshold and improving the electrical and mechanical properties. The nanocomposites Were evaluated for their electrical and mechanical properties and the results were compared with the corresponding binary systems, Le., PU having GNP as the only filler. It was observed that the addition of OMMT at a concentration of around 2 wt%, significantly enhances the electrical and mechanical properties of the nanocomposites with the percolation threshold at much lower concentration of the GNPs. The excellent electrochemical properties arise due to formation of new 3D network (clay-graphite-clay or graphite-clay-graphite) and the synergistic effect between the three components.
