▎ 摘　　要

NOVELTY - The method involves heating (S10) the magnetic metal to gasification to obtain the magnetic metal gas. The magnetic metal gas mixed inert gas is passed (S20) through the high voltage pulse signal region to obtain the negatively charged metal ion. The negatively charged metal ion is collided (S30) to the graphene coated on the negative electrode under the action of the electric field. The negatively charged metal ion is reduced (S40) to be magnetic metal and embedded in graphene after losing the electron. The magnetic metal embedded in the graphene is magnetized (S50) to obtain the graphene-loaded magnetic material. USE - Preparation method of graphene-loaded magnetic material used for manufacturing aviation device and anti-electromagnetic radiation device (all claimed). ADVANTAGE - The magnetic metal is expanded through graphene, so as to reduce the density of the magnetic metal, and to obtain magnetic material with a lower density. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating the preparation process of graphene-loaded magnetic material.
