A simple morphogenesis technique for fabricating stable bionic superhydrophobic surfaces at ambient temperature using copper as a model system is presented. The resulting flowerlike cluster coating of copper fatty acid carboxylates (see figure) has a high contact angle of about 162°. This study opens up new avenues for the industrial fabrication of superhydrophobic surfaces that may be useful in a wide variety of applications.
