Title:
MANGANIC ACID NANO-SHEET ULTRATHIN FILM AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3697513
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a manganese oxide ultrathin film of which the ultrafine film thickness can be controlled in a sub-nanometer range by a method perfectly different from a conventional method, and a manufacturing method therefor.
SOLUTION: A colloid solution in which a manganic acid nano-sheet is suspended and a cationic polymer solution are prepared. A substrate is alternately immersed in these solutions and this immersion operation is repeated to respectively adsorb the nano-sheet and the polymer on the substrate. Both components are alternately and repeatedly laminated at an interval of from a sub-nm to nm level to form a film. Subsequently, the polymer is removed to obtain a manganic acid nano-sheet ultrathin film.
