The generation of “nanograss” surfaces , where the surface chemistry of nanorough silicon is precisely adjusted by the photochemical immobilization of polymeric thin films, is reported. The wetting properties of the surfaces can range from superwetting to impaled drops and superhydrophobicity. Superhydrophobic nanograss is found to be “condensation resistant”.
