Preparation method of electrochemical combined electrode

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 method for preparing an electrochemical combined electrode. Background technique [0002] In electrochemical research and determination, the main research is around the reaction process that occurs on the surface of the electrode, so the electrode and its preparation method have an irreplaceable position in the electrochemical field. Electrochemical experiments are usually a three-electrode system. The counter electrode, working electrode, and reference electrode are independent of each other, and the position is not fixed. The distance between the electrodes has a greater impact on the measurement results, and affects the reproducibility of the electrode measurement, and the electrochemical cell volume It is small, usually only a few milliliters. The exposed electrodes are easy to contact and short-circuit during the measurement, causing serious damage to the electrochemical workstation. There are reports of composite electrodes ...

AI Technical Summary

Problems solved by technology

Electrochemical experiments are 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. At the same time, the volume of the electrochemical cell Small, usually only a few milliliters, the exposed electrodes in the measurement are easy to contact and short circuit, causing serious damage to the electrochemical workstation

There is a composite electrode that has been reported (Chinese Patent No.: 03137469.7), but it is only suitable for water phase use, and its integration level is low; due to the use of glass packaging, it is not suitable for the packaging of alloy electrodes due to the limitation of packaging materials, and the packaging process consumes a lot of energy. , easy to break, poor temperature resistance, difficult to clean, high production cost, etc.
