1
Independentgraphenegraphene roll-to-roll coating apparatus
An apparatus for coating a metallic member with graphene, comprising: a ﬁrst roller that continuously supplies the metallic member; a pre-treating unit that performs a surface treatment on the metallic member supplied through the ﬁrst roller as the metallic member passes continuously through the pre- treating unit, wherein the pre-treating unit performs, on the surface of the metallic member supplied from the ﬁrst roller, a process for removing impurities from the metallic member that includes a plasma process and a laser process, and further wherein at least one partition wall is provided within the pre-treating unit between an area where the plasma process is performed and an area where the laser process is performed, to thereby prevent the impurities from passing between the area where the plasma process is performed and the area where the laser process is performed; a graphene forming unit including at least one gas nozzle conﬁgured to deposit reactant gas directly onto a treated surface of the metallic member to form a graphene ﬁlm on the treated surface of the metallic member, as the metallic member passes continuously through the graphene forming unit; and a second roller that collects the metallic member coated with the graphene ﬁlm after the metallic member passes through the graphene forming unit, wherein within the pre-treating unit. the area where the pl asma process is performed and the area where the laser process is performed are conﬁgured and arranged such that the plasma process is performed be fo re the laser process.
