Preparation of a Super-Hydrophobic and Self-Cleaning Coating for an Anti-Icing Transmission Line

The super-hydrophobic coating with self-cleaning property was prepared by particle-filling method based on nanometer SiO 2 (n-SiO 2 ) and TiO 2 (n-TiO 2 ) as filler. The surface properties of the coating were tested by contact angle (CA) goniometer and atomic force microscopy (AFM). The results indicate that the contact angle (CA) of the coating is above 160°. The surface of the coating possesses a natural lotus-like micro-and nanohierarchical structure. The CA is recovered gradually from 85° to 138° with procedure the photocatalytic degradation of the oil pollutant for 7 hours. The adhesive force between the coating and icing decreases about 80% compared with that of bare glass surface and icing.
