Abstract

Abstract: Addition of inorganic particles and insulating polymeric materials to conducting polymers allows the alteration and modification of physical properties of the conducting polymer. An inverse emulsion polymerization technique was employed for the synthesis of polyaniline (PANI), composites of PANI with copper (PANI‐Cu), polyvinyl alcohol (PANI‐PVA), as well as composites of PANI with Cu and PVA (PANI‐Cu‐PVA) under comparable experimental conditions. The FTIR and UV/Vis, spectra were employed to determine the chemical structure. The morphology of the synthesized composites was studied by SEM technique. The XRD pattern illustrates good crystallinity of the composites with improved conductivity at room temperature. The TGA results show an increase in the thermal stability of the composites. The results show that co‐addition of PVA and Cu into PANI greatly affects the properties of PANI as well as the solubility as the composites were soluble in a number of commonly used organic solvents such as DMSO, NMP, chloroform, 2:1 mixture of chloroform and 2‐propanol, and 2:1 mixture of toluene and 2‐propanol.
