ORGANIC SOLVENT DISPERSION CONTAINING FLAKY TITANIUM OXIDE, METHOD FOR PRODUCTION OF THE DISPERSION, TITANIUM OXIDE FILM USING THE DISPERSION, AND METHOD FOR PRODUCTION OF THE TITANIUM OXIDE FILM

摘要

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 single layer of a titanium oxide nanosheet closely 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.
