Tunable materials

A corrosion resistant material comprising:

• a substrate;
• a first material comprising:
• less than about 90% of an amino group or epoxy group;
• between about 0.05% and about 50% siloxane;
• between about 5% and about 80% nanoparticles, microparticles, or macroparticles;
• and
• between about 0.1% and about 5% of a first functionalized graphitic material, wherein the first functionalized graphitic material comprises:
• a sacrificial metal particle selected from the group consisting of magnesium, aluminum, zinc, nickel, cobalt, and combinations thereof;
• a first molecule chemically bound to the first functionalized graphitic material, the 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;
• a second molecule chemically bound to the first functionalized graphitic material, the second molecule comprising a third group, a second spacer, and a fourth group, wherein the third group is a different group from the first group, wherein the 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, wherein the sacrificial metal particle is bound to either the first group or the third group, wherein either the first group or the third group is bound to the substrate, wherein the group bound to the substrate is different from the group bound to the sacrificial metal particle, wherein the second group and the fourth group are chemically bound to the first functionalized graphitic material;
• a second material comprising:
• less than about 90% of a silyl group;
• between about 0.05% and about 50% siloxane;
• between about 5% and about 80% nanoparticles, microparticles, or macroparticles;
• and
• between about 0.1% and about 5% of a second functionalized graphitic material;
• a third material comprising:
• less than about 90% of an amino group or epoxy group and a silyl group;
• between about 0.05% and about 50% siloxane;
• between about 5% and about 80% nanoparticles, microparticles, or macroparticles;
• and
• between about 0.1% and about 5% of a third functionalized graphitic material;
• a thermoset plastic chemically bound to the amino or epoxy group of the first material, and the third material;
• and
• a monomer of an elastic polymer to chemically bound to the silyl group of the second material, and the third material, wherein the first material, the second material, and the third material are attached to the substrate.
