Abstract

Abstract: Polyaniline can be used as an electrode because it is a conductive polymer whose conductivity can be adjusted through a doping-dedoping process. This study aimed to synthesise polyaniline film for use as a substrate for Fe-Ni alloy electrodeposition. A polyaniline layer was synthesised using the galvanostatic technique with a current of 1 mA in three-electrode cells. The results of Fourier transform infrared analysis showed that the deposit formed was the emeraldine salt phase of polyaniline. The formation of a polyaniline deposit was confirmed by differential scanning calorimeter and X-ray diffractometer. The scanning electron microscope micrograph showed that the layer growing on the substrate was porous polyaniline, which had uniform morphological characteristics. This polyaniline was used as a substrate in the electrodeposition of FeNi alloys and produced a uniform silvery layer even though it grew above the porous substrate.
