Document Type and Number:
Japanese Patent JP2020138879
Kind Code:
A
Abstract:
To provide a modified graphene with low defect concentration, a resin composite, and a dispersion.SOLUTION: A modified graphene has an intensity ratio (g/d) of G and D bands in Raman spectra of 1 or more and is of formula (I): Gr1-Ar1-X1-(Y1) n1(I) [Gr1 is graphene, Ar1 is a C6-18 arylene group, X1 is a single bond, or a group with a carbon atom in a C1-20 alkylene group or a C1-10 alkylene group substituted with a structure selected from -O-, -NH-, -CO-, -COO-, -CONH-, and an arylene group, Y1 is an atom or group that binds a carbon atom in Ar1 when X1 is a single bond or binds a carbon atom in X1 when X1 is not a single bond, where Y1 is selected from hydrogen, halogen, a C1-6 fluoroalkyl group, a cyano group, a nitro group, an acyl group, an amide group, a vinyl group, a carboxylic acid group, a carboxylate ester group, a phosphate group, a C3-6 alkylsilyl (ether) group, and a siloxane group. n1 is an integer of 1 or greater].SELECTED DRAWING: None
