| description | The present invention relates to a manufacturing method of a three-dimensional microporous graphene having a high specific surface area from fluorinated polyimide by using a laser carbonization technique, and its application to a micro supercapacitor electrode manufactured by the method. More specifically, the present invention relates to a manufacturing method of a composite flexible electrode having a microporous graphene layer, which comprises: a polymer film preparation step to prepare a fluorinated polyimide film; a laser irradiation step of irradiating one or more surfaces of the polymer film with a laser beam; and a graphene layer forming step to form a microporous graphene layer on a surface of the polymer film by irradiating the laser. The present invention also relates to a composite flexible electrode having a microporous graphene layer manufactured by the method and a micro supercapacitor comprising the same.
