Title: Graphene nanodispersion and method for preparing same

Abstract: An ionic liquid can disperse graphene at a high concentration. The ionic liquid can be represented by general formula (1): ##STR00001## in which R.sub.1 and R.sub.5 may be the same or different and each independently represents a substituted or unsubstituted C1-7 linear or branched alkyl group; R.sub.2 is represented by formula (2): ##STR00002## in which R.sub.6 and R.sub.7 may be the same or different and each independently represents a C1-4 linear or branched alkylene group, and m represents an integer of 1-5; R.sub.3 and R.sub.4 may be the same or different and each independently represent a hydrogen atom, substituted or unsubstituted C1-4 linear or branched alkyl group; X.sup.- represents a counter ion; and n represents 0-30.
