Супергидрофобная поверохность на основе ксерогеля из углеродных нанотрубок

Abstract

A technology of creating a hydrophobic coating out of crumb obtained by xerogel milling based on carbon nanotubes is proposed. This provides simplicity of application - the crumb is glued to the protected object. The hydrophobicity is ensured by the lotus effect due to the surface of the agglomerates of carbon nanotubes and separate nanotubes protuding outside of the agglomerate limits. A contact angle of 152 degrees and a sliding angle of 3 degrees are achieved. The coating possesses good conductivity and can also be used for static removal or heating through electricity.
