【摘要】 目前用来探测海洋微弱的电场信号的传感器主要以固态银-氯化银电极为核心，为适应海底复杂的环境，提高探测电极的性能，使用石墨烯和石墨烯/银纳米复合材料对Ag/AgCl海洋电场探测电极进行改性。通过在粉压成型的全固态Ag/AgCl电极中添加一定含量的石墨烯/银纳米复合材料，增加了Ag/AgCl探测电极在海水中反应界面的比表面积，电极电势更加稳定，极差稳定变得更快，降低了电极自噪声，优化了电极的各项性能指标。可以满足在低频微弱的海洋电场的条件下的探测和快速部署的要求。为新型电极的创新研制提供了新的思路，也可为无机化合物作为电极添加材料的探索研究提供参考和借鉴。本发明为新型电极的创新开发提供了新的设计方向，也可为无机化合物作为新型电极材料添加剂的开发提供了参考。更多还原

【Abstract】 At present, the sensors used to detect the weak electric field signals in the ocean are mainly based on solid silver-silver chloride electrode core. In order to adapt to the complex environment of the seabed and improve the performance of the detection electrode, the Ag/AgCl ocean electric field detection electrode is modified with graphene and graphene/Silver nanocomposite materials.The specific surface area of Ag/AgCl detection electrode in seawater was increased by adding some graphene/Silver nanocomposites into the all-solid Ag/AgCl electrode formed by powder pressing. The electrode potential was more stable, the range stability became faster,the self-noise of the electrode was reduced, and various performance indexes of the electrode were optimized.It can meet the requirements of detection and rapid deployment under the condition of low frequency Marine electric field.The invention provides a new design direction for the innovative development of new electrode, and also provides a reference for the development of inorganic compounds as new electrode material additives.更多还原
