中文摘要： 微波-红外兼容隐身材料需要满足微波吸收强度大、红外发射率低、厚度薄、质量轻、吸收频带宽等要求，还原氧化石墨烯基三维多孔纳米复合材料的研究是实现这些要求的一个重要方向。基于氧化石墨烯表面含有丰富的含氧官能团、特殊的片状结构，导电高分子聚1-萘胺的结构可设计性、电导率易调控、红外发射率较低等特性，拟以氧化石墨烯为模板，分别通过原位溶液聚合方法合成还原氧化石墨烯/聚1-萘胺二元三维多孔纳米复合材料，乳液聚合和水热反应两步法制备还原氧化石墨烯/聚1-萘胺/金属氧化物（Fe3O4、Co3O4、TiO2、ZnO、SnO2等）三元三维多孔纳米复合材料。探索复合材料的合成工艺条件、材料组成、界面结构、金属氧化物纳米粒子的种类及形貌、多孔结构等对复合材料的电磁参数及微波-红外兼容隐身性能的影响，阐明复合材料的红外辐射及微波吸收机理，为制备结构新颖、综合性能优良的石墨烯基微波-红外兼容隐身材料奠定理论基础。

英文摘要： Microwave-infrared compatible stealth materials need to meet the strong absorption of microwave, low infrared emissivity, thin depth, light weight, and broad absorption band, et al requirements. The study of reduced graphene oxide-based three-dimensional porous nanocomposites is an important direction to achieve these requirements. Due to the rich oxygen-containing functional groups on the surface and special sheet structure of graphene oxide, conducting polymer poly(1-naphthylamine) with good structure designability, easily controlled electrical conductivity, low infrared emissivity characteristics, this project plan to use graphene oxide as a template, reduced graphene oxide/poly(1-naphthylamine) binary three-dimensional porous nanocomposites were synthesized by in-situ solution polymerization, while reduced graphene oxide/poly(1-naphthylamine)/metal oxide (Fe3O4, Co3O4, TiO2, ZnO, and SnO2, et al) ternary three-dimensional porous nanocomposites were prepared by a two-step method: emulsion polymerization and hydrothermal reaction, respectively. In order to clarify the infrared radiation and microwave absorption mechanism and lay a theoretical foundation for construction novel structure, excellently overall performance of graphene-based microwave-infrared compatible stealth material, the effects of synthetic technological conditions, material composition, interfacial structure, type and morphology of metal oxide nanoparticles, porous structure on the electromagnetic parameters and microwave-infrared compatible stealth performance of composite materials were explored.
