▎ 摘　　要

NOVELTY - A shielding filler comprises a melamine sponge as a carrier whose surface is covered with iron oxides (FeOx)/graphene, where the iron oxides are preferably present in the following form such as iron, iron(II) oxide, iron(III) oxide or iron(II, III) oxide, the iron oxides (FeOx) accounts for 5-99% of the total mass of the shielding filler, and graphene accounts for 1-95% of the total mass of the shielding filler. USE - Shielding filler for use in train, airplane, ship or transformer and electromagnetic shielding material, and shielding coating for fabric (all claimed). ADVANTAGE - The shielding filler has sponge macropore structure, electric loss and magnetic loss, and electromagnetic shielding performance.
