Abstract:

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·m2·kg-1,可以作为吸波隐身材料的新型功能型填料。
