英文摘要	Degradation of organic coatings caused by microorganisms limits the application of anti-corrosive coatings in harsh marine environments. In this study, a novel superhydrophobic coating was developed to prolong the durability and integrity in marine environments. Superhydrophobic basalt scales were obtained using a set of simple methods, including chemical etching by a concentrated NaOH solution and fluorination using 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PFDTES). Then, the superhydrophobic basalt scales were arranged on top of the epoxy resin base to produce the superhydrophobic composite coating (3 mu L water droplet; contact angle of 164.9 degrees). After 21 days of immersion in Pseudomonas aeruginosa (P. aeruginosa) inoculated media, the results of antibacterial testing and electrochemical characterization in an erosive environment showed that superhydrophobicity significantly inhibited the adhesion of the P. aeruginosa cells and enhanced the corrosion resistance of the composite coating.
