摘要

In a composite of Al and an electroconductive polymer (I), the surface of the Al to which (I) is bonded has a predominantly (HOO) crystal face (H = 1, 2, 4). (I) is (substd.) polyaniline (IA). (I) is deposited by electrolytic deposition on an Al redn. electrode with (HOO) surface. This surface may be etched first. (I) is depositing by contacting the oxidised form with a reducing medium, which may be a nonmetal or metal. (IA) is deposited on an Al electrode at +0.75 to +0.95 V vs. SCE in 3-6 N aq. acid (mixt.) contg. H2SO4, HCl and/or HBF4.
