A method for forming a coating on aluminum by contacting the aluminum with water, at least one multifunctional polymeric organic acid, a monomer of an intrinsically conductive polymer and polymerizing the ICP monomer and forming aluminum oxide by imposing an electrical potential between the aluminum surface as the anode and a cathode. The intrinsically conductive polymer salt and aluminum oxide coating that is formed resists corrosion and is resistant to de-doping during immersion in hot water.

Anodically formed intrinsically conductive polymer-aluminum oxide composite as a coating on aluminum

A method for forming a coating on aluminum by contacting the aluminum with water, at least one multifunctional polymeric organic acid, a monomer of an intrinsically conductive polymer (ICP) and polymerizing the ICP monomer and forming aluminum oxide by imposing an electrical potential between the aluminum surface as the anode and a cathode. The intrinsically conductive polymer salt and aluminum oxide coating that is formed resists corrosion and is resistant to de-doping during immersion in hot water.

Organically soluble intrinsically conductive polymer compositions having enhanced electrical conductivity are produced by adding a hygroscopic, water-insoluble plasticizer to an organically soluble intrinsically conductive polymer salt. Polymer blends containing such compositions are also produced by blending a matrix polymer with the plasticizer/ICP salt compositions. Methods for enhancing the electrical conductivity of an organically soluble intrinsically conductive polymer salt provide for the addition of a hygroscopic, water-insoluble plasticizer to an organically soluble intrinsically conductive polymer salt.
