Preparation and Capacitive Properties of Polyaniline/Au Film

Abstract:

Article Preview

Polyaniline (PANI) doped with dodecylbenzene sulfonic acid (DBSA) was synthesized by chemical polymerization method, which was dissolved in toluene to prepare the casting solution (PANI, 0.20% w/w). Before casting the prepared solution on the surface of PET to form PANI films, Au was sprayed onto the PET film. The morphology of the obtained PANI/Au films was characterized by field-emission scanning electron microscopy (FE-SEM). The capacitive performance was characterized by cyclic voltammetry and galvanostatic charge-discharge technique in H2SO4 electrolyte under various conditions. The experimental results show that the specific capacitance of the prepared PANI/Au film can reach 280 Fg-1 in 0.50 M H2SO4 electrolyte within the potential range from 0.000 to 0.650 V vs. SCE. The obtained PANI/Au film has extremely high stability which has no obvious decrease for 30000 cycles.
