Beschreibung
Zusammenfassung:	A method of producing interlayer distance controlled graphene, an interlayer distance controlled graphene composition, and a supercapacitor are provided. A method of producing an interlayer distance controlled graphene involves dispersing a graphene oxide in a solution by using a surfactant, forming a reduced graphene oxide by adding a reducing agent into the solution containing the dispersed graphene oxide, and adding a pillar material that is activated at its both ends by a N2+ group into the solution containing the reduced graphene oxide to control an interlayer distance of the reduced graphene oxide.
