使用T700碳纤维制备了海洋电场探测电极,采用减小放大电路输入阻抗的方式提高电极的稳定性能,减少电极的稳定时间。对不同质量碳纤维电极的电化学性能和探测性能进行表征,分析影响碳纤维电极响应特性的因素。结果表明,比表面积对电极的响应性能影响较大,比表面积越大,电极的电容性能越好,在低频处的系统阻抗越小,电极响应增益越大。

The marine electric field detection electrode was prepared with T700 carbon fiber.The stability of the electrode was enhanced by decreasing input impedance of amplifying circuit,the time required for the electrode to stabilize was reduced.Both electrochemical and exploring performance of different quality electrodes were characterized,the factors that have an impact on the response properties of carbon fiber electrode were analyzed.The results show that the specific surface area plays a great part in the response properties of electrode.The capacitive performance can get better along with the increasing of the specific surface area.In addition,the lower the system impedance at low frequency,the greater the electrode response gain.
