Outline of Final Research Achievements

Effects of water vapor treatment (WVT) on the oxide surface for the wettability conversion to hydrophobicity was investigated. Experimental results revealed that this treatment deteriorates bondings of oxide surface with forming adsorption sites such as OH groups for various hydrophobic agents with OH and COOH groups. The effectiveness of this treatment depends on both oxide materials and the surface modifiers. Comparative study between WVT and vacuum-UV illumination suggested that the WVT is more effective to rough oxide surface or oxide porous materials than vacuum-UV illumination. The hydrophobic porous glass prepared through this treatment became a superhydrophobic material and exhibited excellent static and dynamic hydrophobicity.
