In this work, we have synthesized polyaniline doped with Cu (II) salts and coordination complexes in presence of Aniline was polymerized in presence ammonium persulphate (APS). We varied the concentration of APS and also that of Cu (II) salts and complexes to see the effect of these on the properties of polyaniline. We investigated the effect of the dopant and ligand around Cu (II) ion on the morphology, crystallinity and conductivity of the resultant polyaniline. The products were characterized by UV-Vis, FT-IR spectroscopy, while the morphology and crystallinity were investigated by scanning electron microscopy, and X-ray diffraction studies respectively. Results show that the morphology, crystallinity and conductivity of the doped polyanilines are found to be influenced by nature of ligand.
