ABSTRACT:
The invention relates to the elaboration of an electrode comprising an electrochrome polymer.
The invention provides an electrode coated with a polymer film obtained by electrochemical polymerization of a monomer M, said polymer corresponding to the general formula (M.sup.+ X.sup.- y)n where X.sup.- represents an anion coming from the electrolyte used for the polymerization, the monomer being either a substituted aromatic heterocycle with 5 links containing a single hetero-atom, or an indole substituted on the phenyl nucleus, the substitutions being possibly groups of the alkyl, alkoxyl, hydroxyl, aryl, substituted aryl, halogene, trihalogenomethyl, cyano, amino or dialkylamino type.
