摘　　要：使用石墨烯和粘胶基碳纤维对Ag/AgCl海洋电场电极进行改性,研究了加入不同碳材料对Ag/AgCl电极的表面形貌、电化学性能和响应性能的影响。结果表明,石墨烯-Ag/AgCl电极性能较好,其极差稳定时间缩短至3 h,极差减小至0.05 mV,交换电流密度增大约一个数量级,噪声与Ag/AgCl电极处于同一水平,能够完整地响应1 MHz的电场信号,没有出现波形失真,能够满足低频微弱海洋电场的探测和快速部署的要求。The Ag/AgCl marine electric field electrode was modified by graphene and viscose-based carbon fiber.The effects of different carbon materials on the surface morphology,electrochemical performance and response performance of Ag/AgCl electrode were investigated.The results show that the graphene-Ag/AgCl electrode has better performance that its stability time is shortened to about 3 hours,the difference is reduced to 0.05 mV,the exchange current density is increased by about an order of magnitude.Its self-noise is at the same level compare with Ag/AgCl electrode and it can fully respond to the electric field signal of 1 MHz without waveform distortion.Graphene-Ag/AgCl can meet the detection requirements of low frequency weak marine electric field and rapid deployment.
