• Copper nanoparticles were prepared by chemical reduction method of CuSO 4 in aqueous solution in the presence of polyvinyl pyrrolidone and cetyltrimethylammonium bromide as double capping agents without input of extra inert gases. These nanoparticles with average particle size 61 nm diameter were obtained by varying polyvinyl pyrrolidone concentration. Copper nanoparticles/polyindole composite was further fabricated via a facile in situ polymerization method. The morphology, structure and thermal stability of copper nanoparticles and copper nanoparticles/polyindole composites were studied by different techniques. The effect of copper weight percent on the conductivity of the composite was investigated, and the obtained data exhibited that only 25% weight of copper nanoparticles has the greatest effect in increasing polyindole conductivity. Furthermore, the performance of copper nanoparticles in the alteration of polyindole conductivity was investigated by SEM images.
