Graphene-based dielectric materials and functional devices are hot topics in materials science and high-tech fields. A controllable method for realization graphene-based electromagnetic functional materials is an urgent scientific and technical issue in this field. It is a challenge to accurately tailor material structures to effectively control material properties. The project intends to study a new method for controllable fabrication of graphene hybrid films by atomic layer-molecular layer deposition. This method gives graphene hybrid films prominent variable-temperature microwave absorption performance, thus obtaining a new high-performance absorbing functional material. The project will clarify the variable-temperature electromagnetic response mechanisms of graphene hybrid films, and reveal the essence of electromagnetic attenuation including relaxation, magnetic resonance, electron transport and magnetic eddy current, as well as electromagnetic synergy and its evolution mechanism with temperature. With atomic layer-molecular layer deposition that can accurately tailor the composition and structure of magnetic nanocrystals and conductive polymers, the project will tune the variable-temperature electromagnetic properties and absorption performance. Therefore, effective structural tailoring methods and performance control strategies for the development of new electromagnetic functional materials are provided. The expected results are conducive to the correct understanding and mastery of the physical nature of the variable-temperature microwave response of graphene hybrid materials. More importantly, it is able to provide a scientific basis for the development of new electromagnetic functional materials.
