Abstract: A novel underwater electric field electrode is prepared with T300 carbon fiber heat-treated at 445 ℃, 465 ℃and 485 ℃. The surface chemical state, electrochemical performance and detection performance of electric field electrode in NaCl solution are measured using X-ray photoelectron spectroscopy (XPS), electrochemical workstation and self-made noise measurement system. The impact of heat treatment on surface group content , cyclic voltammetry (CV) characteristics, exchange current density, response performance and electrode settling time is discussed. The detection mechanism of underwater carbon fiber detection electrode is analyzed. The group CO and COOR content of carbon fiber electrode increase as the heat treatment temperature increases; the heat treatment reduces the capacitance effect of electrode, increases its exchange current density, and improve its linear performance and settling speed.
