Abstract:

Nano-structured TiO2 coating was constructed through sol-gel process and dip-coating method on the stainless steel surface using tetra-n-butyl titanate as precursor. The phase and the crystallographic structure of the TiO2 coating were characterized by an X-ray diffractometer (XRD), and the surface topography and structures of the TiO2 coating were characterized by a scanning electron microscope (SEM). The superhydrophobic property of the TiO2 coating modified with the fluoroalkylsilane (FAS, CF3(CF2)7CH2CH2Si(OCH3)3) was characterized by the water contact angles. It was observed that the TiO2 coating showed superhydrophobicity with water contact angle 155.3° after modifying with FAS, and the superhydrophobicity was corrosion-resistance.
