MANUFACTURING METHOD OF REDUCED GRAPHENE OXIDE, REDUCED GRAPHENE OXIDE, MANUFACTURING METHOD OF BARRIER FILM USING THE REDUCED GRAPHENE OXIDE AND BARRIER FILM
MANUFACTURING METHOD OF REDUCED GRAPHENE OXIDE, REDUCED GRAPHENE OXIDE, MANUFACTURING METHOD OF BARRIER FILM USING THE REDUCED GRAPHENE OXIDE AND BARRIER FILM
Provided are a manufacturing method of reduced graphene oxide, reduced graphene oxide manufactured according to the manufacturing method of reduced graphene oxide, a manufacturing method of a barrier film using the reduced graphene oxide, and a barrier film manufactured according to the manufacturing method of a barrier film. More particularly, the manufacturing method of reduced graphene oxide comprises the steps of: dispersing graphene oxide in a polar solvent; preparing a mixture solution by adding an organic solvent to the polar solvent; reducing the graphene oxide by adding a reducing agent to the mixture solution; and removing the polar solvent and the remaining reducing agent by applying a solvent exchange method after the reduction step. The manufacturing method is proper for manufacturing a large quantity of reduced graphene oxide having excellent dispersibility. The barrier film has enhanced barrier properties against moisture and gas.
