NOVELTY - Graphene-iron iron oxide-polyaniline ternary nanocomposite material with adjustable wave absorption properties comprises 10-30 wt.% reduced graphene oxide, 10-60 wt.% polyaniline, and the rest is ferric oxide. The composite material is obtained by reducing graphene oxide-ferroferric oxide binary nanoparticles and aniline through low-temperature polymerization by changing the content ratio of reduced graphene oxide-ferroferric oxide binary composite material and aniline. The wave absorption properties of the corresponding ternary nanocomposite is regulated. The adjustment range of the content ratio of the reduced graphene oxide-ferric tetroxide binary composite material and aniline is 1:0.5-3. USE - Graphene-iron iron oxide-polyaniline ternary nanocomposite material with adjustable wave absorption properties. ADVANTAGE - The graphene-iron iron oxide-polyaniline ternary nanocomposite material with adjustable wave absorption properties is helps to the increase of the content of polyaniline, and gradually increases corresponding ternary nanocomposite material's absorbing strength. The width of the absorbing band has also increased significantly. It has wide application prospects in stealth materials, electromagnetic safety protection and other fields.
