摘　　要：采用化学镀法在碳纳米管表面均匀地镀覆了磁性镍-钴合金层及采用原位法制备了化学镀镍-钴合金碳纳米管/聚吡咯复合吸波材料。采用XRD、TEM、SEM、FT IR及振动样品磁强计等对碳纳米管镀镍-钴合金层的形貌、微结构与磁性能进行了分析,还采用网络矢量分析仪对该复合材料在3~6 GHz频段内的吸波性能进行了研究。结果表明,镍-钴合金层连续、均匀、完整地包覆在碳纳米管表面,化学镀后镀层呈非晶态。通过在碳纳米管表面镀上磁性金属镍-钴合金层可提升碳纳米管/聚吡咯复合材料的吸波性能,其复合材料最大反射率为-20d B。A new composite（ Ni-Co / CNTs / PPy） wave absorbing material was synthesized from the carbon nanotubes（ CNTs） coated magnetic Ni-Co alloy by electroless plating（ Ni-Co / CNTs） and PPy by in situ compositing. The morphology,structure,component and electromagnetic properties of Ni-Co / CNTs were investigated by XRD、TEM、SEM、FT IR and EDS. The microwave reflectivity of Ni-Co / CNTs / PPy was calculated. The results indicated that CNTs had been completely coated with uniform,continuous and amorphous Ni-Co alloy film after electroless plating. It showed the microwave absorption property of CNTs / PPy composite could be improved by Ni-Co alloy coating on CNTs. The maximum refractive index of sample is 20 d B.
