A composite nanosheet characterized by having a molecular film of lamellar structure constituted of a surfactant and, provided along the plane of the molecular film, a metal oxide nanosheet, obtained by causing a mixed solution of surfactant, such as laurylamine, and metal alkoxide to flow on a water surface. Further there is provided a process for producing a metal oxide nanosheet, comprising drying the above composite nanosheet and immersing the same in a solvent in which the surfactant is soluble so that the metal oxide nanosheet is separated from the molecular film. As the metal oxide nanosheet, there can be mentioned a GeO2 nanosheet, SiO2 nanosheet, etc. Various metal oxide nanosheets of uniform thickness can be obtained under mild conditions within a short period of time. |
