<p>A member having an antifouling surface comprising a microscopically dispersed, exposed hydrophobic portion and an hydrophilic portion induced by a photocatalyst. The member according to a first embodiment comprises a substrate and a surface layer provided on the substrate, the surface layer comprising a photocatalytic oxide, a silicone resin or silica, and a water-repellent fluororesin, wherein the silicone or silica and the water-repellent fluororesin are microscopically dispersed and exposed onto the outermost surface of the surface layer. The member according to a second embodiment comprises a substrate and a surface layer provided on the substrate, the surface layer comprising a hydrophobic resin and a photocatalytic oxide, wherein the hydrophobic resin and the photocatalytic oxide are microscopically dispersed and exposed onto the outermost surface of the surface layer and the photocatalytic oxide, by virtue of the photocatalytic activity created upon photoexcitation, is self-hydrophilized or hydrophilizes a photocatalytic oxide present in the vicinity of the above photocatalytic oxide.</p> |
