Claim:
1. A method for providing corrosion protection to a substrate comprising the steps of: providing a substrate; and forming a conductive polymer corrosion protective composite comprising an organic-inorganic component comprising an inherently conductive polymer and an inorganic component and a corrosion inhibitive additive comprising an anodic corrosion inhibitor and a cathodic corrosion inhibitor wherein said anodic corrosion inhibitor is selected from the group consisting of compounds of vanadium, molybdenum, tungsten, and mixtures thereof, wherein the corrosion inhibitive additive is selected from the group consisting of cerrous molybdate with bismuth vanadate, cerous molybdate with strontium tungstate, cerous phosphate with strontium tungstate, bismuth vanadate with bismuth molybdate and strontium tungstate, cerous citrate, zinc molybdate, and strontium tungstate, and mixtures thereof, and wherein said anodic and cathodic corrosion inhibitor are present between 1.0 to 50 wt %, wherein the conductive polymer is present in a concentration of 1 to 10 wt % of the anodic and cathodic corrosion inhibitors, and wherein a metal complexing agent is present in an amount between 0.1 and 1.0 mole fraction of the combined inhibitors; and applying said conductive polymer corrosion protective composite to at least one surface of said substrate.
