Patent ID: 10040946

Abstract:
A functional film manufacturing method, in manufacturing a functional film having an organic layer on a support and an inorganic layer on the organic layer, comprises steps of preparing a coating material containing an organic compound which has a glass transition temperature of 100° C. or higher and is to be the organic layer, and an organic solvent; coating a support surface with 5 cc/m2 or more of the coating material such that the organic layer thickness becomes 0.05 to 3 μm; forming the organic layer by drying the coating material on the support surface such that the coating material has a viscosity of 20 cP or higher and a surface tension of 34 mN/m or less in a decreasing-rate-of-drying state, and curing the organic compound; and forming the inorganic layer on the organic layer surface by a vapor phase deposition method accompanied by generation of plasma.
