▎ 摘　　要

NOVELTY - Suspension comprises a water miscible solvent, graphene flakes and at least one additive having a structure (I). USE - The suspension is useful in the production of electronic materials, electronic articles such as electronic circuits and capacitors such as super caps (super capacitors), electrically conductive films, chemical sensors, optical materials and composite materials such as enhanced and/or electrically conductive synthetic materials, batteries and membranes. ADVANTAGE - The suspension exhibits high electrical conductivity and mechanical stability. DETAILED DESCRIPTION - Suspension comprises a water miscible solvent, graphene flakes and at least one additive having a structure of formula (cR(-Sp-W1)x) (I). cR = 2-7 aryl rings comprising condensed, polycyclic ring system; Sp = spacer having 2-10 atoms of linear chain, where at least a single bond is contained in the linear chain; W1 = functional protonizable, protonated, deprotonatable or deprotonated groups, provided that W1 comprises at least one group comprising polyoxyalkylene groups having at least 3 alkylene oxide units, monosaccharide groups, disaccharide groups, oligosaccharide groups with 3-10 saccharide units, polyoxazoline groups with 3-10 oxazoline units, then W1 is -S(=O)2OH, -S(=O)2NH2,-OP(=O)(ORcR)(OH), -OP(=O)(OH)2, -P(=O)(ORcR)(OH), -P(=O)(OH)2, -O-S(=O)2OH or -S(=O)2OH, where the W1 increases the solubility of additive in water; RcR = optionally branched 1-3C-alkyl (unsubstituted); and x = 1-4. INDEPENDENT CLAIMS are included for: (1) manufacturing a suspension, comprising (a) providing the suspension of graphite in a water miscible solvent, and (b) crushing the graphite under introducing energy into the suspension by ultrasound, ball mill, stirred ball mill, rotor-stator system and/or homogenizer to obtain graphene flakes, where the additive according to (I) is added in the step (a) and/or (b); (2) graphene flakes produced by the method; and (3) use of (I), for the stabilization and/or production of graphene platelets.
