▎ 摘　　要

NOVELTY - Preparing small-size graphene involves selecting layered graphite and water as raw materials for preparing by professional personnel, and treating the raw materials, selecting the layered graphite and water to mix and other treated to make small-graphene water dispersion liquid by professional staff, detecting the prepared small-sized graphene, preparing a treated graphene aqueous solution of the preparing graphene, and performing further treatment on the prepared prepared small size graphene to detect the prepared graphene anqueous dispersion solution, filtering the graphene dispersion fluid to store through the detection result, and filtering out the filtered graphene dispersion liquid to store. USE - Method for preparing small-size graphene. ADVANTAGE - The method is capable of preparing small-sized graphene with stable dispersion, mass production, without using strong acid or strong oxidant, not adding dispersant, no metal ion, avoids the other application system generating negative characteristics, so as to increase graphene and the increasing of the small size graphene the dispersion liquid, reducing the application cost.
