Fabrication and superhydrophobicity of fluorinated titanium dioxide nanocoatings.

This study demonstrates the fabrication of a stable superhydrophobic surface with low contact angle hysteresis (CAH) using an arrangement of nanoscale TiO(2) spheres. The control of precursor quantity is selected as the key factor in determining surface roughness that significantly intensifies water contact angle (CA) of TiO(2) films. After surface fluorination treatment, the anatase-type crystalline surfaces exhibit good water repellency (CA approximately 166.
