▎ 摘  要

NOVELTY - Preparing 3D nanostructure electromagnetic wave absorbing material involves dispersing the metallocene and graphene in acetonitrile to obtain a dispersion, where the metallocene includes nickelocene, ferrocene or cobaltene. The dispersion liquid is subjected to a microwave reaction to obtain product. USE - Method for preparing 3D nanostructure electromagnetic wave absorbing material used in flexible electromagnetic wave absorbing film (claimed). ADVANTAGE - The method has excellent wave absorbing performance and improves the electromagnetic wave absorbing property of the flexible film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electromagnetic absorbing superstructure array, which comprises periodic units, where the each periodic unit comprises five layers of flexible electromagnetic absorbing films, the sizes of two adjacent flexible electromagnetic wave-absorbing films are different, the each layer of flexible electromagnetic absorbing film is the flexible electromagnetic absorbing film or flexible electromagnetic absorbing film.
