Abstract: 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.

Abstract: Provided is an electromagnetic wave absorbent material comprising a magnetic film as the main constituent thereof. The magnetic film comprises a titania nanosheet where a 3d magnetic metal element is substituted at the titanium lattice position. The electromagnetic wave absorbent material stably and continuously exhibits electromagnetic wave absorption performance in a range of from 1 to 15 GHz band and is useful as mobile telephones, wireless LANs and other mobile electronic instruments. The absorbent material can be fused with a transparent medium and is applicable to transparent electronic devices such as large-sized liquid crystal TVs, electronic papers, etc.
