▎ 摘　　要

NOVELTY - The liquid has a graphene, dispersing agent and solvent, where concentration of the graphene dispersion liquid is 1 mg/mL to 60 mg/mL and a dispersant content is 0 to 6%. Length of graphene sheet is 100 to 6000nm, where the graphene is an oligonucleotide layer. The dispersing agent is selected from dodecyl benzene sodium sulfonate, dodecyl sodium sulfonate, styrene sulfonic acid sodium, poly styrene sulfonic acid sodium, lignin sodium sulfonate, sodium dodecyl sulfate, polyvinylpyrrolidone, sodium taurocholate, polystyrene, hexadecyl trimethyl ammonium bromide and polyvinyl alcohol. USE - Graphene dispersion liquid. ADVANTAGE - The liquid possesses better dispersibility and stability, high dispersing concentration, and high production yield. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a Graphene dispersion liquid. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a graphene dispersion liquid.
