▎ 摘　　要

NOVELTY - An ultra dispersed graphene is prepared via liquid nitrogen quenching by taking 0.5-8 mg/mL graphene oxide solution, heating at 30-100 degrees C, quenching in liquid nitrogen until frozen, and heating or carrying out chemical reduction to remove oxygen-containing functional groups. USE - Method for preparing ultra dispersed graphene via liquid nitrogen quenching (claimed). ADVANTAGE - The method is short, low-cost and simple.
