▎ 摘　　要

NOVELTY - Preparation of graphene suspension involves preparing graphene flakes, preparing a polar or nonpolar fluid having same polarity as graphene flakes, and suspending the graphene flakes in the fluid by mixing until the suspension is uniform. The graphene flakes have ratio of surface area with respect to thickness of more than 300 Angstrom , thickness of less than 160 Angstrom , no significant physical surface distortions, and surface polarity. USE - Preparation of graphene suspension (claimed). Uses include but are not limited to transparent electrode of solar cell and flat panel display, additive for battery and supercapacitor electrode, and conductive composite material for electromagnetic wave interference shielding and static charge dissipation. ADVANTAGE - The method enables economical preparation of graphene suspension with excellent mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene suspension.
