Process for preparing anticorrosive coatings comprising functionalized graphite materials

A process for preparing an anticorrosive coating, comprising the steps of:

• providing a substrate;
• providing a sacrificial metal particle selected from the group consisting of magnesium aluminum zinc, nickel, cobalt, and combinations thereof;
• chemically binding a graphitic material to a first molecule comprising a first group, a first spacer, and a second group, wherein the first group comprises at least one of hydroxyl, thiol, amino, epoxy, carboxyl, and silyl, wherein the second group comprises at least one of amino, epoxy, hydroxyl, carboxyl, silyl, and thiol;
• chemically binding said graphitic material to a second molecule comprising a third group, a second spacer, and a fourth group, wherein said third group is a different group from said first group, wherein said third group comprises at least one of thiol, carboxyl, trialkoxysilyl, phosphoryl ester, crown ether, cryptand, dioxime, and N-heterocycle, wherein the fourth group comprises at least one of amino, epoxy, hydroxyl, carboxyl, silyl, and thiol;
• binding said sacrificial metal particle to either said first or said third group;
• binding either said first or said third group with said substrate, wherein said group bound to said substrate is different from said group bound to said sacrificial metal particle;
• chemically binding said second group and said fourth group to said graphitic material;
• growing thermoset resin side chains on said graphitic material;
• and
• growing siloxane side chains on said graphitic material wherein the process further comprises the steps of providing a second graphitic material;
• binding the first and the third groups to the second graphitic material, thus forming a first layer of functionalized graphitic material;
• providing a second layer of functionalized graphitic material;
• and
• providing a third layer of functionalized graphitic material between the first layer and the second layer of the functionalized graphitic material, wherein the third layer of functionalized graphitic material binds together the first and second layers of functionalized graphitic material.
