▎ 摘　　要

NOVELTY - Preparation of magnetoelectric loss absorber derived from magnetic metal MOF comprises weighing metal salt and organic complex at ratio of 1:1, stirring thoroughly in solvent to obtain clear and transparent solution, slowly adding graphene oxide aqueous solution, stirring, transferring to a container, reacting, centrifuging, repeatedly washing, and vacuum oven drying to obtain composite precursor metal MOF and reduced graphene oxide (rGO); and placing in crucible, heating in gas-passing tube furnace, collecting complexes of metal MOF derivative and rGO, mixing with paraffin wax, pressing into a ring in a mold, and measuring electromagnetic wave absorption performance. The magnetoelectric loss absorber is a composite material of magnetic metal MOF derivative and rGO. USE - The method is for preparation of magnetoelectric loss absorber derived from magnetic metal MOF. ADVANTAGE - The composite wave absorbing agent has uniform particle size, complete appearance and good crystallinity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a magnetoelectric loss absorber derived from magnetic metal MOF.
