METHOD FOR PREPARING A DOPED POLYPYRROLE

摘要

The present invention relates to a method for preparing a doped polypyrrole conducting layer on a thick film carbon electrode comprising the steps of depositing a circular shaped silver thick film on a pre-deposited copper film and obtaining a silver conductor layer; depositing a circular shaped carbon thick film on the silver conductor layer and obtaining a carbon electrode; sonicating the carbon electrode in deionized water to clean the carbon thick film surface; preparing an electrolyte solution of hydrophilic organic salt and pyrrole monomer in a polar solvent; and electrodepositing polypyrrole on the carbon electrode with the electrolyte.
