Abstract
Disclosed is a method of manufacturing a porous graphene film representing superior electrical properties. The method includes preparing a graphene/polymer composite dispersed solution by adding polymer particles to a first graphene dispersed solution obtained by dispersing graphene powders into a solvent, manufacturing a graphene/polymer composite film by using the graphene/polymer composite dispersed solution, and manufacturing the porous graphene film by removing the polymer particles from the graphene/polymer composite film.
