▎ 摘　　要

NOVELTY - The method involves loading (S1) the carbon-containing powder into the reaction conduit. The metal wire balls at both ends of the reaction conduit are put (S2) to position the carbon-containing powder in the middle of the reaction conduit. The carbon-containing powder against the conductive electrode is pressed (S3) against the wire mass. The conductive electrode is driven (S4) to conduct electricity during the electric pulse of 1ms-100kms, so that the metal wire group and the carbon-containing powder generate heat and reach 1500K-3500K, so as to obtain graphene. USE - Method for preparing graphene at high temperature by electric pulse. ADVANTAGE - The discharge makes the carbon source and the metal wire group as the heat source, and reaches the temperature of 1500K-3500K in a very short time. The amorphous carbon can be converted into turbo-stacked graphene, which simplifies the preparation process and solves the pain point in graphene industrialization. The production process does not release harmful gases to the environment, which is a green, environmentally friendly and fast technology. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a device for preparing graphene at high temperature by electric pulse. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic flowchart of the method for preparing graphene at high temperature by electric pulse.
