▎ 摘　　要

NOVELTY - The method for producing iron ion-graphene, involves (S1) adding graphene to nonionic chelating penetrating agent to obtain dispersion, (S2) adding ferric chloride, obtaining uniform dispersion of ferric chloride in graphene so that the graphene lattice are reacted with iron ions, (S3) placing the iron ions of the mixed material in a reaction kettle for ion infiltration reaction, (S4) cleaning the generated iron ion-graphene. USE - Method for producing iron ion-graphene for use in package of choke filter component (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for iron ion-graphene comprises iron ions and graphene molecules. The iron ions are embedded in the molecular lattice of graphene.
