Silver coating of iron nanowires is introduced. The morphology, magnetic and electromagnetic interference (EMI) properties are examined in these silver coated iron nanowires. The XRD analysis of Ag/Fe NWs ensures the formation of Fe and Ag. JEOL 2100F TEM/STEM that equipped with Oxford EDS and Gatan EELS for micro-chemical analysis is used to analysis these samples.
The results indicate the layer of silver is not formed on the surface of iron nanowires rather silver nanopartciles. The results of Vibration Sample Magnetometer (VSM) indicate the saturation magnetization of Ag/Fe NWs has greater than 1256 emu/g that is almost four times of pure iron (217.6 emu/g). It shows Silver/Iron nanowires (Ag/Fe NWs) hybrid materials have higher magnetization performance than that iron nanowires. The results of EMI are also revealed the silver coated iron nanowires will enhance the effects of electromagnetic interference.
