▎ 摘　　要

NOVELTY - The preparation method involves providing conductive substrate composed of three-dimensional structure of graphene in graphene dispersion liquid taking electric pulse deposition. A cathode pole piece with positive charge is deposited on a negative pole piece which is set with predefined temperature to obtain one-layer graphene on the surface of silver composite material. An electric pulse deposition process controls the anode and cathode plates which are of predetermined length, external voltage, temperature and deposition time. USE - Preparation method for graphene or silver composite material. ADVANTAGE - Avoids oxidation of graphene structure which avoids damage by using organic solvent ultrasonic peeling graphene, graphene dispersion liquid. DESCRIPTION OF DRAWING(S) - The drawing shows a three-dimensional view of the structure of electric pulse sedimentation tank.
