Composition for conductive polyaniline films and composites, used e.g. in optoelectronic or transparent electrodes, comprises emeraldine base polyaniline and a functionalized sulfonic, phosphonic or phosphoric acid dopant
A composition for the manufacture of conductive polyaniline films or a composite conductive material based on polyaniline, comprises a polyaniline in the form of emeraldine base and a dopant which is a sulfonic, phosphonic or phosphoric acid functionalized with plasticizing groups. A composition for the manufacture of conductive polyaniline films or a composite conductive material based on polyaniline, comprises a polyaniline in the form of emeraldine base and a dopant of formula (I) which is a sulfonic, phosphonic or phosphoric acid functionalized with plasticizing groups. R1 = -SO2(OH), -PO(OH)2 or -OPO(OH)2; R2 = (un)saturated hydrocarbon optionally bearing in its chain aromatic group(s) and/or oxygen atoms, or a cyclic or aromatic hydrocarbon group; R3, R4 = a direct bond or as R2. Independent claims are also included for: (1) a method of preparing a conductive film of polyaniline by thermal treatment of a film of the composition; (2) a conductive polyaniline doped as claimed; (3) a method of preparing a composite conductive material by mixing the composition with a insulating polymer; (4) a composite conductive material with the doped polyaniline dispersed in a matrix of insulating polymer, preferably poly(methyl methacrylate).
