▎ 摘  要

NOVELTY - The method comprises injecting graphene flake separated from graphite into a plasma reactor, heat-treating the graphene flake injected into the plasma reactor at plasma thermal reaction, collecting the heat-treated graphene flake, and reforming and peeling off the graphene flake. The method further comprises re-injecting the graphene flake collected from the graphene flake recovery step in the plasma reactor to remove the oxygen remaining in the graphene flake. The graphene flake is injected into plasma reactor through a metering feeder. USE - The method is useful for manufacturing a transparent electrode material (claimed), which is useful in a flexible display device and a flexible battery. ADVANTAGE - The method is capable of manufacturing the transparent electrode material with improved electrical reliability, transmittance and resistance value. DETAILED DESCRIPTION - The method comprises injecting graphene flake separated from graphite into a plasma reactor, heat-treating the graphene flake injected into the plasma reactor at plasma thermal reaction, collecting the heat-treated graphene flake, and reforming and peeling off the graphene flake. The method further comprises re-injecting the graphene flake collected from the graphene flake recovery step in the plasma reactor to remove the oxygen remaining in the graphene flake. The graphene flake is injected into plasma reactor through a metering feeder, where the flake is supplied with 30-70 liters/minute of central gas, 30-80 liters/minute of a carrier gas, and 5-15 liters/minute of sheath gas during injection. The power condition in the plasma reactor is 10-70 kW. The graphene flake is heat-treated at greater than 4000K under anoxic condition. INDEPENDENT CLAIMS are included for: (1) a transparent electrode; (2) a method for manufacturing the transparent electrode; and (3) a transparent electrode substrate.
