Manufacturing graphene oxide, comprises preparing a dispersion of graphite oxide, removing the graphite oxide from the dispersion of graphite oxide, and then performing an oxidation of graphite oxide to graphene.

BYUN N, LEE D, LEE S

Apparatus, useful to remove e.g. copper from graphene sheet, includes circulation part in which cleaning solution is directly supplied to catalyst metal of graphene sheet along direction parallel to transferring direction of auxiliary tank.

NA D H

Apparatus of removing catalyst metal on graphene sheet used as transparent electrode film of e.g. flexible display, controls holder to exercise in the state that is completely sunk under catalyst metal cleaning solution.

YOON J H, NA D H

Apparatus, useful for preparing graphene-structured material for e.g. filler, comprises supply hopper to supply graphite oxide, supply line of which end is fixed to hopper, and reducing atmosphere gas supply unit connected to supply line.

JI B K, CHOI J Y, SHIN C M

Manufacture of reduced graphene oxide used for transparent electrodes of e.g. storage batteries, involves dispersing graphene oxide in solvent to obtain dispersion solution, adding ammonia borane to dispersion solution, and refluxing.
