抄録

<p>Some nanostructures using a transition metal oxide such as CuO, which is attracting attention as a pseudo-capacitive material, is applied to the electrode surface. In this research, one of the nanostructures, CuO nanowire was synthesized by thermal oxidation method. In addition, influence of the fabrication conditions on capacitance of supercapacitor electrode was investigated. In order to investigate the influence, morphological observation, wettability evaluation, and cyclic voltammetry were conducted for the CuO nanowire specimen. As a result, depending on the production conditions, differences were observed both in the wettability of the specimen surface and in the results of cyclic voltammetry. The surface of the CuO nanowire specimen heated for 6 and 8 hours showed hydrophilicity, on the other hand that heated for 2 and 4 hours showed hydrophobicity. Only the specimen heated for 6 hours with hydrophilicity showed good electrochemical properties. Consequently, it became clear that the conditions for synthesized the test piece by the thermal oxidation method affect the wettability of the test piece surface which affects the performance of the supercapacitor electrode.</p>
