Elaboration and characterization of ITO electrode modified by transition metal dispersed into polyaniline thin films

The morphology of the obtained composites shows a uniform dispersion of nickel particles onto the polyaniline matrix and reveals that the immersing times of complexation has a significant effect on the amount of incorporated particles. The impedance spectroscopy study reveals that the conductivity of the composite film increases with the amount of nickel incorporated. UV-vis and FTIR results confirm the presence of PAni and Ni particles on the electrode surface.
