Superhydrophobicity: Making Superhydrophobic Surfaces with Microstripe Array Structure by Diffusion Bonding and Their Applications in Magnetic Control Microdroplet Release Systems (Adv. Mater. Interfaces 21/2017)

In article number 1700918, Jian Cao and co-workers introduce a new method to fabricate a superhydrophobic surface with a micro-stripe array structure. The cover illustrates this surface that can be used in a magnetic control micro-droplet release system. The fabrication process, based on diffusion bonding and selective corrosion, is shown at the bottom. The hierarchical structure of this surface is demonstrated in the background by a SEM image of CuO grown on the copper bulges.
