A facile method for the fabrication of super-hydrophobic surfaces and their resulting wettability

Stable, flower-like super-hydrophobic surfaces on copper substrate were fabricated by means of a facile method using one-step solution immersion. The contact angles (CAs) of the surfaces with test liquids were >150°, and scanning electron microscopy showed hierarchical micro- and nanostructures. X-ray diffraction pattern revealed that the as-fabricated surface was crystallized and was of sheet structure, which can be observed in a layer structure.
