▎ 摘　　要

NOVELTY - Preparing modified graphene conductive material involves taking graphite block as original material, melting the graphite block into the organic solution to obtain a mixed solution, and then placing the mixed solution on the heating platform for heating treatment. The prepared solution heated to a certain temperature is oscillated with an ultrasonic oscillator to peel off the graphite block from the inside out to obtain a multilayer graphene solution. The multi-layer graphene solution is separated and purified to obtain a single-layer graphene solution. The obtained single-layer graphene solution is added to the modifier, mixed and stirred uniformly to obtain the modified graphene. USE - Method for preparing modified graphene conductive material. ADVANTAGE - The method prepares the modified graphene conductive material in a simple, cost-effective and eco-friendly manner with reduced consuming the carbon atoms contained in the graphene, and excellent integrity of the graphene structure, and improved quality of graphene improves the conductivity of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for testing modified graphene conductive materials, which involves: (A) preparing multilayer graphene solution by method for preparing graphene modified coating material; (B) filtering and purifying to obtain a multilayer graphene solid; (C) loading the graphene fixed body into a dedicated conductive test container; and (D) packing and compacting the obtained single-layer graphene fixed body into another dedicated conductive test container.
