Abstract

An electrochemical synthesis method for a cobalt oxide / polyaniline composite material includes the following processing steps of mixing a mixed solution containing 0.1mol / L of aniline and 0.5mol / L of sulfuric acids and another mixed solution containing 0.1mol / L of cobalt sulfate and 0.5mol / L of sulfuric acids based on the proportion of 1:2, adjusting the potential of hydrogen (pH) value of the mixed solution by the sulfuric acids until the pH value reaches to 1.0 to 2.0, adding 0.3g / L of cetyl trimethyl ammonium bromide, stirring with a magnetic stirrer, and performing an electropolymerization at the constant potential of 1.5V to 5.0V and at the temperature of 10 DEG C to 25 DEG C for 3 to 15 minutes to obtain the cobalt oxide / polyaniline composite material. According to the electrochemical synthesis method for the cobalt oxide / polyaniline composite material, the cobalt oxide / polyaniline composite material which is uniform, compact and good in corrosion resistance can be obtained on surfaces of conducting glass and stainless steel.
