▎ 摘　　要

NOVELTY - Preparing graphene by electrochemical method involves intercalating and expanding graphite paper by using graphite paper as a positive electrode and an aqueous solution of an intercalating agent as an electrolytic solution to obtain expanded graphite paper. The expanded graphite is filtered, washed and then carried for ultrasonic peeling off process to obtain flocculent graphene slurry. The graphene slurry is filtered and then dried by using a microwave vacuum drier to obtain fluffy graphene powder. USE - Method for preparing graphene by electrochemical method (claimed). ADVANTAGE - The method enables to prepare graphene by electrochemical method in simple and cost effective manner and the product consumes less energy.
