Superhydrophobic surfaces are often found on plant leaves and insect wings in nature. Water on these surfaces forms small beads with a high contact angle of greater than 150° and drips off rapidly when the surfaces are slightly inclined. This interesting phenomenon has stimulated extensive research to make artificial superhydrophobic surfaces and to employ them for a variety of applications. A key challenge in making superhydrophobic surfaces is to tailor the morphology of the surfaces in nanometer scales, which typically involves synthesis and fabrication of materials at nanometer dimensions. In this paper, we will first explain general design principles for fabricating superhydrophobic surfaces, with a specific focus on how to fabricate superhydrophobic surfaces on intrinsically hydrophilic materials. We will then present several fabrication methods developed in our group during the past several years for making artificial superhydrophobic surfaces following such design principles.
