▎ 摘　　要

NOVELTY - Preparation of nano-dispersed graphene oxide comprises preparing graphene oxide solution (0.01-1 g/L), adding cationic polyelectrolyte, stirring uniformly, putting mixed polyelectrolyte/graphene oxide solution, and ultrasonically crushing to obtain stable dispersed graphene oxide solution. USE - Method of preparation of nano-dispersed graphene oxide (claimed). ADVANTAGE - The method can reduce graphene oxide to nanometer scale from micron scale, and stable.
