Wetting of silicon nanograss: From superhydrophilic to superhydrophobic surfaces
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 drop and superhydrophobicity. Super hydrophobic nanograss is found to be condensation resistant".
