Titanium dioxide (TiO2) nanorods were deposited on silicon substrates using titanium tetra-isopropoxide as a precursor via a metal-organic chemical vapor deposition method. TiO2 nanorod film thickness was about 3.8 mu m, and the observed contact angles of the TiO2 surface were very low due to their super-hydrophilic properties. As a next step, TiO2 nanorods were treated for 24 h with stearic acid molecules. Surface wettability changed from hydrophilic to hydrophobic by stearic acid treatment and the contact angle of TiO2 nanorod film after treatment was approximately 119 degrees. (c) 2013 Elsevier B.V.
