Abstract
Polyaniline film was synthesised by electropolymerization method to produce conductive layer as a substrate for NiCo alloy preparation. The obtained film was characterised by Fourier transform infrared spectrometer (FTIR), X-ray diffractometer (XRD), scanning electron microscope (SEM) and differential scanning calorimeter (DSC). The electrodeposited polyaniline was emeraldine base with cross-linking and crevice morphology. The film was then employed as working electrode in NiCo electrodeposition. Morphological analysis showed a uniform surface of the metallic deposit was successfully grown onto the polyanyline film with Ni and Co composition of 59.66 wt.% and 29.47 wt%, respectively. This result shows the future application of the electroplymerised polyaniline as a host material for fabrication of ferromagnetic alloy using electrodeposition technique.
