▎ 摘　　要

NOVELTY - Broadband double-layer electromagnetic wave absorbing material, comprises matching layer and a wave absorbing layer, where the matching layer is made of carbon material/silver-polyaniline composite material, and the wave absorbing layer is ordered mesoporous carbon material. The carbon material is graphite powder or graphene. USE - Used as broadband double-layer electromagnetic wave absorbing material. ADVANTAGE - The broadband double-layer electromagnetic wave absorbing material effectively expands the effective wave-absorbing bandwidth of the material, and enhances the absorption of the incident electromagnetic wave, so as to effectively resist the effect of the electromagnetic wave. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of broadband double-layer electromagnetic wave absorbing material.
