摘要	Bio-inspired superhydrophobic coatings are of increasing interest in marine corrosion protection due to their superior barrier and shielding effects. However, some difficult problems like weak mechanical strength, the use of costly and toxic reagents, and intricate preparation processes have long hindered the practical application of the superhydrophobic coatings. Herein, a durable, self-cleaning and anti-corrosion superhydrophobic coating based on epoxy resin matrix was successfully fabricated, avoiding the use of fluorine materials. The prepared coating possessed excellent superhydrophobicity and was applicable to a variety of substrates, which was ascribed to the effect of modified kaolin particles on lowering surface energy. Through SEM and LSCM, the superhydrophobic coatings manifested the morphology feature of "hills +mountain", which could store air to reduce solid-liquid contact. The prepared coating had been proven to have greater impedance modulus and charge transfer resistance by EIS test, and displayed outstanding durability in salt spray environment compared with pure epoxy coating. In addition, the sandpaper abrasion, standard cross-cut tape and self-cleaning tests indicated that the superhydrophobic coatings satisfied robust mechanical stability and excellent resistance to contaminants, laying the foundation for the application of superhydrophobic coating in practical environment.
