Preparation and basic property of super hydrophobic coating based on semiconductor film

The insulators coated with super-hydrophobic coating have good performance of anti-icing. But the super-hydrophobic coating can´t completely preventing ice accumulation, especially the soft rime. In order to solve this problem, a kind of semiconductor coating was prepared in this paper,and then the super-hydrophobic coating was structured on the semiconductor film,and the basic property of this kind of composite anti-ice coating was tested. The results show that the semiconductor film have good insulation performance,the temperature of semiconductor film can be raised 3~6°C under high voltage and the water contact of the super-hydrophobic coating surface can reach to 155°. The combination of the super-hydrophobicity of the super-hydrophobic coating and the electric heating property of the semiconductor film are expected to solve the anti-icing problem of the insulators on the transmission line completely.
