  Wettability control of a solid against a liquid is widely investigated in industry for application to daily life because it can produce various physical and chemical phenomena related to solids and liquids, achieving beneficial purposes. Recent researches revealed that static and dynamic wettability are affected by nano-scale surface characteristics on the solids, and the importance of the viewpoint from materials science is gradually increasing in this topic. This paper presents a short review of the studies on the superhydrophilicity of TiO₂ photocatalyst, processing and properties of superhydrophobic materials, and control of dynamic hydrophobicity, mainly of the past decade of our group.
