Flexible composite Ag-AgNWs-CF as low noise marine electric field sensor

Carbon fibers (CF) have triggered extensive interest with the progress of multifarious marine electric field sensor devices owing largely to their high flexibility, good conductivity and exceptional chemical/thermal stability. Herein, flexible Ag/sliver nanowires (AgNWs)/CF (Ag-AgNWs-CF) electrodes with extremely tiny potential difference drift of 67.22 μV/24 h have been successfully fabricated by a facile alcohol-thermal method with a reaction temperature of 170℃ for 120 min. The conductive AgNWs was introduced to the CF as a coating material. The AgNWs with three-dimensional (3D) network and silver particles accounts for superior areal specific capacitance and low Tafel slope for the composite electrodes (CEs). Using such flexible Ag-AgNWs-CF as a marine electric field sensor, the excellent self-noise was obtained, which signifies prospective ability to respond to weak signals.
