METHOD FOR PRODUCING THIN FILM CONSISTING OF NANOSHEET MONOLAYER FILM BY SPIN COAT METHOD, AND HYPERHYDROPHILIZED MATERIAL, SUBSTRATE FOR OXIDE THIN FILM AND DIELECTRIC MATERIAL OBTAINED THEREFROM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a thin film consisting of nanosheet monolayer film(s) and use of the thin film obtained thereby.SOLUTION: A method for producing a thin film consisting of nanosheet monolayer film(s) by a spin coat method comprises a step of preparing an organic solvent sol formed by allowing nanosheets obtained by the exfoliation of an inorganic layered substance to be dispersed in an organic solvent; and a step of 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.
