Electrochemical Polymerisation of Aniline on Skeleton Nickel Electrodes

The polyaniline(PAni)coating was electrochemically deposited on nickel skeleton electrode and nickel foil by potential sweep between − 0.2 V and 1.2 V/SCE, with a scan rate of 20 mV s−1; acid aqueous solutions containing 0.027 mol L−1aniline in 1 mol L−1sulphuric acid were used. The PAni film was studied by IR Spectroscopy, UV-VIS Absorption, Scanning Electron Microscopy, X-Ray Diffraction and Cyclic Voltammetry. The X-Ray studies suggest that the PAni films present a good cristalinity, as well as high molecular weight, possible high or intermediate crosslinked.
