▎ 摘　　要

NOVELTY - Preparing graphene/carbon nano tube/iron-containing compound/polymer coating type microwave absorbing material involves mixing graphene, carbon nanotube, polyvinylpyrrolidone and N-methyl pyrrolidone ultrasonically. Iron-containing compound and polymer are added to mixed liquid to obtain the graphene/carbon nano tube/iron-containing compound/polymer coating type microwave absorbing material. USE - Method for preparing graphene/carbon nano tube/iron-containing compound/polymer coating type microwave absorbing material (claimed). ADVANTAGE - The method enables to prepare graphene/carbon nano tube/iron-containing compound/polymer coating type microwave absorbing material that has excellent microwave absorbing performance.
