GRAPHENE TRANSPARENT ELECTRODE AND METHOD FOR MANUFACTURING THE SAME

PURPOSE: A graphene transparent electrode and a manufacturing method thereof are provided to be convenient and economical by using a metal board for manufacturing of a transparent electrode and to be applicable to the electronic products which require high conductivity such as a next generation electrode, a transparent conductive film, a solar cell, a radiator, an anti-static coating, and a sensor. CONSTITUTION: A manufacturing method for a graphene transparent electrode is composed of the following: a step(S100) of providing a graphene oxide solution; a step(S200) of drying the graphene oxide solution after the graphene oxide solution is coated on a metal board; a step(S300) of obtaining a reduced graphene oxide by firstly reducing the graphene oxide with a reductant; a step(S400) of forming a reducing layer by secondly reducing the reduced graphene oxide where the reduced graphene oxide is heat-treated under an inactive atmosphere; a step(S500) of compressing a transparent film onto the reducing layer; and a step(S600) of etching the metal board with an etching liquid. The metal is copper, aluminum, nickel, iron, or zinc.
