Integration of Carbon Nanotubes Electrodes on Glass Substrate
Abstract:
Carbon nanotubes electrodes were prepared in the holes of glass directly by microwave plasma chemical vapor deposition. During the process of carbon nanotubes growth, the negative bias imposed on the substrate could improve the alignment of carbon nanotubes. The electrochemical behavior of CuSO4 at the carbon nanotubes electrode was investigated. Compared to graphite electrode, carbon nanotubes had excellent electrochemical behavior for the analysis of Cu2+. The current had linearship with the Cu2+ concentration in the range of 0.01~0.30 mmol•L-1, and the correlation coefficient was 0.9975. Because carbon nanotubes were integrated directly on the substrate, the stable response to Cu2+ solution showed that the carbon nanotubes electrodes had long-term stability.
