Surface uniformity evaluation method of modified Ag/AgCl ocean electric field electrode based on SVET

The surface uniformity of the ocean electric field electrode directly affects the performance of the electrode. In order to study the electrode surface uniformity, scanning electron microscope and scanning vibration electrode testing (SVET) were carried out for the graphene modified Ag/AgCl electrode. Based on the SVET results, a method for measuring and characterizing the surface uniformity of the electrode was proposed, and the surface uniformity of the modified Ag/AgCl electrode was quantitatively evaluated with the average value and standard deviation of the electrode potential as the evaluation indexes. The evaluation results were consistent with the results of scanning electron microscope.
