Modified graphene, method for producing modified graphene, modified graphene resin composite, modified graphene sheet and modified graphene dispersion

摘要

PROBLEM TO BE SOLVED: To provide a modified graphene, a resin composite, and a dispersion having a low defect concentration. A modified graphene having a structure represented by the following formula (I) and having a ratio (g / d) of a G band intensity g and a D band intensity d in a Raman spectral spectrum of 1 or more: Gr1 = N-Ar1-X1- (Y1) n1 (I) (In formula (I), Gr1 is a single-layer graphene or multi-layer graphene, Ar1 is an arylene group having 6 to 18 carbon atoms, and X1 is a single bond. It is a linear, branched or cyclic alkylene group having 1 to 20 carbon atoms, and Y1 is an atom or group bonded to at least one carbon atom in the arylene group when X1 is a single bond, or When X1 is not a single bond, it is an atom or group bonded to a carbon atom in X1, n1 represents an integer of 1 or more, and when n1 is 2 or more, Y1 is the same group but different groups. There may be.) [Selection diagram] None
