Abstract
Methods of forming a conductive aluminum substrate comprise anodizing a surface of an aluminum substrate to form a porous alumina surface layer, contacting the alumina surface layer with a liquid dispersion or solution of a polymer or at least one polymer-forming component, under conditions sufficient for the polymer to seal pores of the alumina surface layer, and removing excess polymer from the alumina surface layer. The resulting sealed conductive aluminum substrate is useful in photoconductors, for example of the dual layer type.
