采用化学镀制备镀镍纳米石墨微片（Ni-nanoG），对其进行制备工艺研究及结构表征，旨在得到一种新型导电导磁填料。讨论了硫酸镍浓度、次亚磷酸钠浓度、温度、pH值对石墨微片镀层的影响，得出镀镍的最佳工艺。采用SEM、XRD、EDS对其结构进行了表征，并用振动样品磁强计（VSM）测试了其磁性能。结果表明：纳米石墨微片（nanoG）表面镀上了一层紧凑的金属镍。镍均匀分布在nanoG的表面和边界面上，将nanoG包覆得较严实。Ni-nanoG厚度约为150nm。nanoG上镍的含量较高，其质量分数大约为34．08％。Ni-nanoG的饱和磁化强度为71．2A·m^[2]·kg^[-1]，可以作为吸波隐身材料的新型功能型填料。
Ni plating graphite nanosheet （Ni- nanoG） was prepared by electroless plating method. The technology of preparation of Ni - nanoG and the microstructures of Ni - nanoG were studied to obtain a novel magnetic conductive filler. The influence of Ni sulfuric acid concentration, sodium hypophosphite concentration, temperature, pH value on the deposition quality of Ni on graphite nanosheet （nanoG） and the optimum technology were researched. The microstructures of the as- obtained samples were characterized by SEM, XRD and EDS. The magnetic property of Ni- nanoG was studied via the vibrating samplemagnetometer （VSM）. The results indicate that a layer of compact Ni coate on the surface of nanoG and the Ni is homogeneously dispersed on the surface and boundary of nanoG. The thickness of Ni - nanoG is about 150 nm. The content of Ni in Ni - nanoG is high and the amount of Ni is about 34.08%. The saturated magnetic strength of Ni - nanoG is 71.2 A.m2 .kg 1. The Ni - nanoG can be used as a new functional filler.
