Title:
ELECTRODE HAVING OUTER COATING FOR CARRYING OUT ELECTROLYTIC METHOD AND PROTECTING INTERMEDIATE COATING ON ELECTROCONDUCTIVE SUBSTRATE AND PREPARATION THEREOF
Document Type and Number:
Japanese Patent JPS5773192
Kind Code:
A
Abstract:
The electrode with an outer coating for effecting an electrolytic process is provided with a protective intermediate coating consisting of a conducting insoluble polymer network formed in situ on a titanium base and containing a small amount of finely dispersed platinum group metal catalyst. A method of manufacturing the electrode comprises applying to the titanium base several layers of a solution containing a polymer precursor and a platinum metal compound which are thermally converted to the protective polymer coating, on which the outer coating is formed, more particularly by electrodepositing manganese dioxide. The polymeric intermediate coating serves to protect the titanium base from oxidation, and to more particularly provide stable electrode performance with economical use of precious metal.
