Abstract: A method for manufacturing a graphene powder capable of minimizing aggregation of graphene particles and a graphene powder manufactured using the same are disclosed. The method includes preparing a graphene solution in which graphene particles are dispersed in a solvent, aggregating the graphene particles, separating the aggregated graphene particles from the solvent, and drying the graphene particles.

Abstract: A method for manufacturing graphene using light capable of transferring and patterning graphene, and graphene manufactured using the method are disclosed. The method includes forming a graphene layer on a catalyst metal layer, attaching a support layer losing adhesion by light on the graphene layer, removing the catalyst metal layer, disposing a substrate on the graphene layer, and separating the support layer from the graphene layer by irradiating light to the support layer.
