▎ 摘　　要

NOVELTY - The preparation method involves adding sodium nitrate (NaNO3), sulfuric acid (H2S04), potassium permanganate (KMn4), water solution and distilled water to natural crystalline flake graphite, performing centrifugal washing of graphene oxide dispersion liquid, adding graphene oxide solution as surface active agent and cross-linking agent, adding carbon black to obtain graphene oxide carbon black, and adding plant oil in graphene oxide carbon black solution by ultrasonic emulsifier to obtain oxidized graphite alkene liquid crystal liquid. USE - Preparation method for graphene oxide liquid crystal liquid. ADVANTAGE - Enhances stability of liquid, and improves desalting capacity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram illustrating graphene oxide liquid crystal liquid preparation process.
