▎ 摘　　要

NOVELTY - Preparing graphene dispersed solution involves preparing graphene precursor, dispersing the prepared graphene precursor in a flask containing water, adding an amine precursor and a non-aqueous organic solvent to obtain mixed solution, placing dean-stark trap and condenser into flask, stirring to conduct a dehydration reaction, and cooling the solution at room temperature, and dehydrating reaction to obtain final product. USE - Method for preparing graphene dispersed solution. ADVANTAGE - The method enables to prepare graphene dispersed solution in cost-effective and environment-friendly manner.
