To provide a method for producing a thin film consisting of nanosheet monolayer film(s) and use of the thin film obtained thereby.The method for producing a thin film consisting of nanosheet monolayer film(s) by a spin coat method according to the invention comprises a step for preparing an organic solvent sol formed by allowing nanosheets obtained by the exfoliation of an inorganic layered compound to be dispersed in an organic solvent; and a step for dropping the organic solvent sol onto a substrate and rotating the substrate using a spin coater. Preferably, the nanosheet size, the organic solvent sol concentration and the spin coater rotation speed are controlled.

A high dielectric nanosheet laminate is produced by laminating nanosheets, each of which has a thickness of 10 nm or less and is formed of an oxide that has a perovskite structure wherein at least four NbO6 octahedrons, TaO6 octahedrons or TiO6 octahedrons are included in a unit lattice. Consequently, the high dielectric nanosheet laminate is capable of achieving a high dielectric constant and a satisfactory insulation property, which are preferable for high dielectric nanosheet multilayer capacitors or the like, at the same time even if formed very thin.

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 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.
