Abstract

Disclosed is an organic dispersion comprising a flaky titanium oxide particle having a high crystallinity and high light permeability contained in an organic solvent. The dispersion can be prepared by a method comprising preparing an aqueous dispersion of a flaky titanium oxide particle containing an organic cation, centrifuging the aqueous dispersion to produce a precipitate, and adding the precipitate to an organic solvent, or a method comprising lyophilizing the aqueous dispersion to produce a lyophilized material and mixing the lyophilized material to an organic solvent. When the organic dispersion is used, it becomes possible to form a film comprising a monolayer of a titanium oxide nanosheet densely arranged therein by such a simple manner that the dispersion is coated on a base material and drying the dispersion. The film thus produced has a photocatalytic activity and a super-hydrophilic property.
