摘　　要：通过浓硝酸氧化法制备了碳纤维海洋电场探测电极,利用水下电场发生装置,对制备的碳纤维电极的水下电场响应性能进行表征。结果表明,相比于未处理的碳纤维电极,经过浓硝酸氧化处理的碳纤维电极能够准确响应1 mHz^10 Hz频率范围内的水下电场信号,线性度提高了近98%。从线性度与灵敏度综合考虑,浓硝酸氧化2 h制备的碳纤维电极水下电场响应性能最佳。The carbon fiber field electric field detection electrode was prepared by concentrated nitric acid oxidation method.The underwater electric field response performance of prepared electrodes was characterized through an underwater electric field generating device.The results show that the carbon fiber electrode treated by concentrated nitric acid can accurately respond to the electric field signal of1mHz-10Hz compared with the untreated carbon fiber electrode,and the linearity has improved nearly by98%.The electrode under oxidation in concentrated nitric acid for2h has the best response performance in the view of both linearity and sensitivity.
