摘要：

A biomimetic hybrid surface based on superhydrophobic polymer microscopic structured surfaces with metal microdomains as hydrophilic components was reported. The hybrid surface was prepared by nickel electroless plating of self-organized honeycomb-patterned polystyrene-based films (HP film) formed by breath figuring, and successive simple peeling of the plated HP film. The HP film consists of hexagonally ordered array of microcavities having a center-to-center interval of about 10 μm and many narrow pillars that hold the top and bottom porous layers together. The thermal-treated water droplet of 5.5 mg remained strongly attached to the hybrid film even when the surface was inverted, whereas the same mass of a water droplet before thermal treatment rolled off the hybrid surface with a sliding angle of 75°. The apparent contact area decreased gradually on further evaporation of the droplet.
