Fabrication of Superhydrophobic Surfaces of Titanium Dioxide and Nickel through Electrochemical Deposition on Stainless Steel Substrate

Abstract

Binary microstructures at both micro- and nano-scale are constructed by the electrochemical depositing Ni and TiO2 on the stainless steel surface. Superhydrophobicity is achieved with a water contact angle greater than 150° after modifying the textured surface with fluoroalkylsilane (FAS-17, CF3(CF2)7CH2CH2Si(OCH3)3). The morphology of the Ni-TiO2 compound coating is studied by scanning electron microscopy.
