Exceptional atmospheric corrosion inhibition performance of super-hydrophobic films based on the self-propelled jumping behavior of water droplets

Super-hydrophobic surfaces have attracted much attention for their potential applications based on the lotus effect, especially in corrosion protection. However, the lotus effect has limited application given its high dependence on external forces, such as gravity and wind force. The self-propelled...

description	Super-hydrophobic surfaces have attracted much attention for their potential applications based on the lotus effect, especially in corrosion protection. However, the lotus effect has limited application given its high dependence on external forces, such as gravity and wind force. The self-propelled jumping behavior of water droplets, a newly found phenomenon over super-hydrophobic surfaces, would bring an alternative mechanism to atmospheric corrosion protection. Two different super-hydrophobic surfaces with a cone-shaped array microstructure and a flower-shaped hierarchical microstructure, respectively, were designed over copper substrate with an electrodeposition method. The dynamic growth and coalescence behavior of droplets were compared over the two super-hydrophobic surfaces. The cone-shaped array microstructure facilitates the self-jumping behavior of micro-droplets over the super-hydrophobic surface.
