<p>[Problem] To provide a novel ionic liquid capable of dispersing graphene at a high concentration. [Solution] An ionic liquid represented by general formula (1). (In the formula, R1 and R5 may be the same or different and each independently represents a substituted or unsubstituted C1-C7 straight-chain or branched alkyl group; R2 is represented by formula (2), where R6 and R7 may be the same or different and each independently represents a C1-C4 straight-chain or branched alkylene group, and m represents an integer of 1-5; R3 and R4 may be the same or different and each independently represents a hydrogen atom or a substituted or unsubstituted C1-C4 straight-chain or branched alkyl group; X- represents a counter ion; and n represents 0-30.)</p> |
