▎ 摘　　要

NOVELTY - Preparing wave-absorbing material comprises using mixed solution of the organic iron salt and the triethylene glycol preparation graphene as the mixed solution of the organic iron salt and the triethylene glycol, carrying out boiling reflux treatment to the mixed solution, separating the dry liquid obtained after the boiling and refluxing treatment to obtain the composite wave absorbing material of the graphene. USE - The wave absorbing material is used as electromagnetic wave absorbing material in microwave band communication (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for wave absorbing materialcomprising graphene sheet of two-dimensional structure, the ferrite nano-particles that particle size is distributed in 4-10 nm to be dispersed on the graphene sheet.
