PREPARATION METHOD OF GRAPHENE TRANSPARENT THIN FILM USING LAYER-BY-LAYER ASSEMBLY PROCESS OF REDUCED GRAPHENE OXIDE

摘要

The present invention relates to a method for producing a graphene transparent thin film using a layered self-assembly of reduced graphene oxide and to an application to an organic light emitting device (OLED) using a graphene transparent thin film obtained according to the manufacturing method, the graphene transparent thin film The manufacturing method of the graphene sheet can be easily and easily inserted into the graphene sheet by layer self-assembly using the electrostatic interaction between the nanosheets of the oppositely charged reduced graphene oxide. Since it can be precisely controlled in terms of sheet resistance, it can be usefully used as a transparent electrode in an OLED device.
