▎ 摘　　要

NOVELTY - Preparing graphene nanoplatelets involves mixing graphite in liquid phase having green exfoliants, exfoliating graphite with high cutting and ultrasonic cavitation in the mixing system, and stabilizing graphene nanoplatelets by incorporating exfoliant. USE - Method used for preparing graphene nanoplatelets as raw material (all claimed). ADVANTAGE - The method offers graphene nanoplatelets having 40-80% graphene with excellent properties and preventive chemical modification during the process of preparation, low costs, no negative environmental effects, and favorable final disposal of the toxic chemicals used in production.
