Conducting polymer nanoparticle composites

An anti-corrosive conducting polymer nanoparticle composite in powder form comprising:

• (i) conducting polymer nanoparticles, wherein the conducting polymer is polyaniline;
• and
• (ii) a substrate particle comprising an external surface and pores with an internal surface, wherein the conducting polymer nanoparticles form a noncontiguous layer in the internal surface of the substrate particle, said substrate particle comprising one or more of epoxy, cation exchange resin particles, nylon, polyester, polyvinyl chloride, polystyrene, polyethylene, and polypropylene resin particles,
• wherein the conducting particle nanoparticles have a diameter of about 3.5nm to about 500 nm;
• wherein the substrate particle has a diameter larger than 1 micron;
