| Popis: | Electroless plating was utilized to deposit nickel nanoparticles on the reduced graphene oxide (RGO). By adjusting the nickel salt precursor concentration, three kinds of Ni-RGO with different nickel contents were synthesized, namely Ni-RGO-1, Ni-RGO-2 and Ni-RGO-5. Transmission electron microscopy and X-ray diffrac- tion were employed to study the surface morphology and crystal structure of as-prepared Ni-RGO. The electro- magnetic performance of graphene oxide and Ni-RGO was characterized. The results indicated that the permit- tivity of Ni-RGO was above 8, almost three times higher than that of pristine graphene oxide. Ni-RGO-1 exhib- ited the best electromagnetic wave absorption performance, although the concentration of nickel precursor is the lowest one among three samples. The minimal reflection loss was up to -24.5 dB for Ni-RGO-1 with a thickness of 2 mm. |
