Problems solved by technology

In electrochemical experiments, it is usually a three-electrode system. The counter electrode, working electrode, and reference electrode are independent, and the positions are not fixed. The distance between the electrodes has a great influence on the measurement results, and affects the reproducibility of the electrode measurement. Small, usually only a few milliliters, the exposed electrodes in the measurement are easy to contact and short circuit, causing serious damage to

Abstract

This invention relates to a method for processing electrochemical combination electrodes sealed by the nm flexible epoxy resin material including: 1, inserting a working electrode matrix material into a conductive support copper rod wrapped with an insulation pyrocondensed tube, a hole Ag reference electrode is welded to the support copper rod, the bottom of a hole Pt counter-electrode is welded to the support copper rod, the hole Ag reference electrode, the hole Pt counter-electrode and the working electrode matrix are arrayed from inside to outside with the working electrode at the middle, the tops of which are at a same plane, the support copper rods of them are fixed by a pyrocondensed tube and put into a die set and fixed, 2, casting the nm flexible epoxy resin material onto the die set to deaerate and cure it, 3, taking out the electrode after cooling it and polishing it.

Description

technical field [0001] The invention belongs to a preparation method of an electrochemical combination electrode. Background technique [0002] In electrochemical research and measurement, the main research is around the reaction process on the surface of the electrode, so the electrode and its preparation method have an irreplaceable position in the field of electrochemistry. In electrochemical experiments, it is usually a three-electrode system. The counter electrode, working electrode, and reference electrode are independent, and the positions are not fixed. The distance between the electrodes has a great influence on the measurement results, and affects the reproducibility of the electrode measurement. Small, usually only a few milliliters, the electrodes exposed during the measurement are easily contacted and short-circuited, causing serious damage to the electrochemical workstation. There is a composite electrode that has been reported (Chinese Patent No.: 03137469.7)...
