One-step fabrication methods toward superhydrophobic (SH) coatings are recognized as very cost-efficient. However, most of the emerged one-step methods rely on the organic solvents to dissolve low surface energy material, which might bring serious environmental issues. In this work, a water-based one-step electrodeposition route was provided to obtain high-performance SH coating on various materials and output functional products such as the mesh used for oil–water separation, a self-cleaning “blackboard”, or stain-resistant cloth; all can be prepared within 5 min. An unconventional lauric acid emulsion containing metal ions served as the electrolyte, and with the appearance of an ultrasonic field, the organic part was effectively co-deposited. The coated SH surface enjoyed excellent mechanical stability and corrosion-resistance property. Profitably, the electrolyte can be repeatedly utilized for several cycles. Besides, our experiment proved that this technique was really scalable, rendering it with great potential for quantity production.
