  • Self healing anti corrosive coatings and a process for the preparation thereof
    Patent number: 9683109
    Abstract: The present invention provides self-healing anti corrosive coatings comprising composites of conducting polymers, chitosan and silica particles along with epoxy useful for corrosion prevention under highly corrosive medium like 3.5% NaCl. Tafel plots exhibits significantly high corrosion protection efficiency (99.99%) for the epoxy coatings with 2.0 wt % loading of chitosan-polymer composite. The weight loss measurements and salt spray test results clearly exhibit superior corrosion resistance offered by coatings with chitosan-polymer composite. The synergistic interaction between chitosan and polypyrrole in the composite is expected to improve the corrosion resistance properties of the coatings. The SiO2 particles present in the composite reinforce the integrity of the coating under corrosive conditions.
