Abstract—The fundamental of electrophoretic deposition (EPD) technique concerns on the use of liquid base colloid to prepare suspension. The pitfall of water based colloid medium has been a tendency for hydrolysis process to occur. Nevertheless, alternating current electrophoretic deposition (AC-EPD) enables water base colloid to be used and at the mean time controls the hydrolysis effect. This study evaluates the effectiveness of deposition thin film Multi Wall Carbon Nanotubes-Polyaniline (MWCNTs-PANi) nanocomposite using AC-EPD. The results were compared with direct current electrophoretic deposition (DC-EPD). FESEM image of AC-EPD shows denser MWCNTs-PANi deposition on nickel substrate. MWCNTs-PANi molecular structures were observed by FTIR analysis. MWCNTs-PANi deposited by AC-EPD consequence to higher specific capacitance and energy density compared to DC-EPD. Specific capacitance of MWCNTs-PANi nanocomposite via AC-EPD and DC-EPD were 22.9 F g-1 and 10.8 F g-1 respectively. Meanwhile, the energy density of AC-EPD is 0.0023 Wh kg-1 whereas the energy density of DC-EPD is 0.0011 Wh kg-1. This study points out that the AC-EPD has more advantages than DC-EPD technique.

Index Terms—Alternating current, carbon nanotubes, electrophoretic deposition, polyaniline.
