膨胀石墨表面化学镀镍及性能

Property of Electroless Nickel Plating on Expanded Graphite

采用化学镀法对膨胀石墨表面镀镍。对包覆后的样品进行了SEM、EDS、XRD、IR和磁性能表征。结果表面,膨胀石墨表面被镍层均匀包覆,其质量分数镍占94.12%、磷占5.88%,镀覆后产品在近红外波段反射率明显增大,磁性能明显增强,饱和磁化强度σs=26.3 A.m2/kg、剩磁σr=8.1 A.m2/kg、σr/σs=0.31,分析结果表明其属于软磁性材料。

Electroless plating of nickel was used to plate nickel on expanded graphite surface.The plated expanded graphite was characterized by SEM,EDS,X-ray Diffraction,IR,vibrating sample magnetometer.The results indicate that an even layer of nickel was plated on expanded graphite.Ni accounted for 94.12% and P accounted for 5.88%.The reflectivity was increased in the near infrared region.The magnetism capability was enhanced.The magnetization and the retentivity were 26.3 A·m^2/kg and 8.1 A·m^2/kg respectively.The σr/σs was 0.31.The obtained material belongs to soft magnetism material.
