Superhydrophobic self-healing intelligent nano-coating and preparation method thereof

The invention discloses a superhydrophobic self-healing intelligent nano-coating and a preparation method thereof. According to the intelligent nano-coating, a sol-gel self-assembly nanoparticle coating is adopted as a framework; functionalized nano-grade silica particles are doped in the coating; magnesium alloy corrosion inhibitor molecules paeonol are loaded in the functionalized nano-grade silica particles; a superhydrophobic fluorine-containing monomolecular film layer is modified on the surface of the particles. With the superhydrophobic characteristic, the coating has a good waterproof performance, and assists in inhibiting corrosive medium penetration. The intelligent nano-coating layer can sense the pH change and magnesium ion existence when the magnesium alloy micro-area corrosion occurs, and can rapidly release the magnesium alloy corrosion inhibitor paeonol. The paeonol molecules can form a layer of dense film adhering to the damaged magnesium alloy surface and inhibiting corrosion spreading. Therefore, a function of actively protecting the magnesium alloy is realized. Further, the superhydrophobic self-healing intelligent nano-coating is adapted to environment changes. Especially, with the Mg<2+> response characteristic, the nano-coating has a good application prospect in the field of magnesium corrosion inhibition.
