A droplet on superhydrophobic surfaces forms a nearly perfect spherical pearl with contact angle higher than 150^o. Tin-doped indium oxide (ITO) nanorods were fabricated on ITO substrate via radio frequency (rf)-magnetron sputtering deposition, and their height was approximately 700nm. For hydrophobization of ITO nanorods surface, the prepared ITO nanorods were treated under a liquid phase with perfluorodecyltrichlorosilane (PFS) self-assembled monolayers (SAMs). Although the ITO nanorods are very hydrophilic, they could become superhydrophobic by modifying them with a coating of PFS. Static, advancing and receding contact angles of ITO nanorods were measured by a contact angle analyzer in order to demonstrate superhydrophobicity of ITO nanorods. The structural and morphological properties of ITO nanorods were investigated by performing scanning electron microscopy (SEM) and atomic force microscopy (AFM).
