Novel conductive nano-composite ink based on poly aniline, silver nanoparticles and nitrocellulose

Abstract

CONDUCTING polymers have attracted much attention in view of scientific interest, simple preparation method and practical applications. This article demonstrates the preparation of an electrically conductive composite based on (poly aniline, silver nanoparticles, nitrocellulose resin) by mixing the three components with each other by sonication. Poly aniline (PANI) doped with HCl was prepared by chemical oxidation pathway using potassium peroxydisulphate while silver nanoparticles (Ag-NPs) was synthesized via chemical reduction process using oleic acid and oleyl amine. The prepared materials were characterized by spectroscopic measurements (FTIR, UV-vis, TEM), in addition to thermal analysis (TGA, DSC). The electrical conductivity was measured by four-point probe method. The achieved results indicated high performance properties for the nano-composite to be applied in conducting inks.
