Özet

The CuO, MgO and Al2O3 films were deposited on Cu, Mg and Al substrates by the Successive Ionic Layer Adsorption and Reaction (SITAR) method. While the MgO thin film showed hydrophilic behavior with contact angle of 75, the Al2O3 film was hydrophobic with the contact angle of 117 degrees. The best enhancement in terms of the wetting behavior was obtained from the copper oxide films. For these films, maximum static water contact angle was 164 degrees. Results showed super-hydrophobic property and unique shape of form. Moreover, the superhydrophobic surface of CuO film exhibited higher corrosion resistance than MgO and Al2O3 films.
