Methods for producing a thin film consisting of nanosheet monolayer film(s) by spin coat methods, and hyperhydrophilized materials, substrates for an oxide thin film and dielectric materials obtained therefrom

摘要

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.
