Preparation and electromagnetic property for microwave absorbing of nickel nanowires

Nickel nanowires were prepared by direct current electrodeposition within the nanopores of anodic alumina membrane. The topography and texture of the nanowires were characterized by SEM, XRD and TEM. It is found that the nickel nanowires are the structure of single crystalline with a preferred orientation along the [111] direction. Microwave electromagnetic experiment demonstrated that the nickel nanowires are dielectrical dissipation materials of which the dielectrical dissipation is 0.55 at 9.5 GHz. The nickel nanowires can be considered as a candidate for microwave absorbing material.
