▎ 摘　　要

NOVELTY - Preparing graphene involves dispersing the graphite in an aqueous surfactant solution to obtain mixed solution. The ultrasonic-stripping is carried out with the mixed solution to obtain a graphene dispersion I. The graphene dispersion I is subjected to jet stripping to obtain a graphene dispersion liquid II. The graphene dispersion II is dried to obtain graphene. USE - Method for preparing graphene used in vehicles, sensors, conductive material and thermal materials (claimed). ADVANTAGE - The method enables to prepare graphene in simple and cost-effective manner, which has excellent performance.
