▎ 摘　　要

NOVELTY - Preparation of high-concentration liquid-crystal single-layer graphene oxide dispersion, involves completely stripping 0.05-5 g/L, preferably 1-2 g/L single-layer graphene oxide dispersion in a membrane separation device, concentrating in a cross-flow filtration manner in a continuous cyclic process, and obtaining concentrated dispersion. USE - Preparation of high-concentration liquid-crystal single-layer graphene oxide dispersion (claimed). ADVANTAGE - The method is simple, continuous, economical and efficient, and provides dispersion of uniform and stable sheets of graphene oxide orderly arranged in monodispersed state. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for high-concentration liquid-crystal single-layer graphene oxide dispersion.
