Abstract
Electrically conductive rubber (ECR) was prepared through conventional rubber mixing techniques on a two-roll mill, which the conductive filler was polymer-coated Cu nano-disk and conductive carbon black (CCB). The effect of Cu nanoparticles content on the mechanical and electrical resistivity properties of ECR was further investigated. The obtained results of six different compositions for ECR with 0, 5, 10, 15, 20 and 25 per hundred of rubber (phr) of Cu nanoparticles loading were compared. It was found that ECR has lower volume resistivity and high tensile strength, compared with rubber containing commercial Cu particles. These results suggest that when the Cu particles are nano-disk and surface modified, the mechanical and stability properties of the rubber can be synchronously improved.
