Abstract
Abstract Based on biological inspiration, we proposed a simple method for preparing anti-corrosion and super-hydrophobic coating. The modified TiO2 compounded ZnO and epoxy resin were prepared by one-pot method. The surface morphology, resistance, super-hydrophobicity, repairability, impedance, wear resistance, etc. of the prepared material were performed by SEM, FTIR, electrochemical workstation, contact angle, rolling angle measuring instrument and simple homemade devices. As a result, it was found that the coating had full-thickness hydrophobicity, its WCA was up to 155.6°, and its repairability was good. Even in a harsh environment, it still had a long working life. At the same time, it had been found that the key to prolonging the anti-corrosion life of the coating lies in the reduction of the volume of the free polymer, the degree of cross-linked curing of the metal-polymer interior and its bonding with the metal substrate.
