  • Device with microbubble-induced superhydrophobic surfaces for drag reduction and biofouling prevention and device for biofouling prevention
    Patent number: 8671862
    Abstract: A device with microbubble-induced superhydrophobic surfaces for drag reduction and biofouling prevention includes an anodic microporous plate, a cathodic microporous plate, and a DC power supply. The anodic microporous plate and the cathodic microporous plate are mounted to a hull surface of a ship. The DC power supply includes a positive pole electrically connected to the anodic microporous plate and a negative pole electrically connected to the cathodic microporous plate. Seawater is electrolyzed to generate hydrogen microbubbles adjacent to a surface of the cathodic microporous plate and to generate oxygen microbubbles adjacent to a surface of the anodic microporous plate, forming superhydrophobic surfaces on the surfaces of the anodic microporous plate and the cathodic microporous plate. Electric current flows through the anodic microporous plate and the cathodic microporous plate to prevent biofouling.
