Abstract:

A technique for obtaining reduced graphite oxide (RGO) with Ni nanoparticle dispersed on the surface via chemical vapor deposition (CVD) method was reported. XRD and SEM observations were carried out to confirm the microstructure of Ni/RGO composite. Magnetic property of Ni/RGO was characterized by vector network analyzer. The influence of Ni(NO3)2 concentration on micromorphology and microwave absorbing property were also discussed. As the concentration of Ni(NO3)2 is 1.5 mol/L, the range of the reflection loss (RL) less than -5 dB is 9 GHz, of which the max value reaches -40 dB.

Key words: nickel, graphite oxide, nanocomposite material, microwave absorbing
