Abstract
Provided are a method of manufacturing graphene, graphene manufactured by the method, a conductive thin film including the graphene, a transparent electrode comprising the graphene, and a radiating or heating device comprising the graphene. The method includes: preparing a graphene member including a base member, a hydrophilic oxide layer formed on the base member, a hydrophobic metal catalyst layer formed on the oxide layer, and graphene grown on the metal catalyst layer; applying water to the graphene member; separating the metal catalyst layer from the oxide layer; and removing the metal catalyst layer using an etching process.
