NOVELTY - Preparing chiral polypyrrole/iron oxide/graphene complex material comprises adding chiral camphor sulfonic acid to the polypyrrole/iron oxide/graphene complex for doping to obtain a chiral polypyrrole/iron oxide/graphene complex material. USE - The complex material is useful for the development of absorbing materials (claimed). ADVANTAGE - The method: adopts a chemical one-step method in graphene to generate polypyrrole and ferrite; and reduces chemical process steps, and reduces production costs. The complex material has good absorbing properties and high-efficiency broadband absorption bands, and can be widely used in civil and military fields.
