Abstract

The concentrated nitric acid oxidation was chosen as the surface treatments on carbon fibers in this paper. Treated carbon fibers were subjected to subsequent processing and forming, the electrodes applied in marine electric field detection were prepared. The electrochemical properties that related to practical application in marine electric field detection such as potential stability, polarization and cyclic voltammetry performance, the electrochemical impedance and the self-noise were characterized, thus an electrochemical evaluation system was formed to optimize the oxidation technology. Combining with the TGA and FTIR, the physical properties of carbon fibers were characterized and some oxidation laws were induced. The results indicate that the carbon fiber electrode prepared by oxidation 4 hours at 110 ℃ has the best electrochemical performance for detection.
