摘　　要：通过原位氧化聚合法制备了聚苯胺-石墨烯纳米复合材料。利用XRD、FTIR以及SEM和TEM对所制备的纳米复合材料进行表征,利用矢量网络分析仪对电磁性能进行分析。结果表明:聚苯胺与石墨烯之间存在较强的相互作用,PANI纳米粒子互相缠绕并镶嵌在石墨烯表面,平均粒径为100 nm左右;与纯聚苯胺相比,聚苯胺-石墨烯复合材料的吸波性能得到了显著提高。PANI-Graphene nano-composites was preparedby in-situ polymerization.XRD,FTIR,SEM and TEM vector Network Analyzer were used to characterize the nano-composites.Results showed that there is a strong interaction between polyaniline and graphene,and the PANI nano-particles were embedded in the surface of graphene,with an average diameter of about 100nm.The absorbing properties of PANI-Graphene composites have been significantly improved than pure PANI.
