Broadband micro-wave absorption properties of Ni-P coated Fe nanoparticles by electroless plating process
Fe nanoparticles with shell of Ni-P coating layer were successfully synthesized using Ni electroless plating process.Electromagnetic-wave absorption of Ni-P coated Fe nanoparticles has been investigated.In contrast to earlier reported materials,the absorption amplitude of as-prepared samples is found not largely decrease with increasing absorption-layer thickness.A reflection loss (RL) exceeding-20 dB can be obtained for almost the whole frequencies within the 2-18GHz range by choosing an appropriate layer thickness between 0.9 and 6.0mm.The broadest bandwidth (RL<-10dB) from 12.5 to 18GHz,covering almost the whole Ku-bands(12-18GHz),is obtained for 1.1mm layer.At the same time,it is worth noticing that in a thin thickness range 0.91-2.0mm,the reflection loss (RL) exceeding-10 dB in the 6-18GHz range is obtained,which covers half of C-bands (4-8GHz),the whole X-bands (8-12GHz) and Ku-bands (12-18GHz).
