EM Properties in Composites with the Filler of Electroless-synthesized Ni-P Powder

摘要

Nickel-phosphorus (Ni-P) powders of different sizes, from nanometer to micrometer, were successfully synthesized using electroless plating method. The parameter determining the particle size is also studied. Composites are fabricated by mixing metallic powder with epoxy at certain volume fraction. The dispersions of permeability and permittivity for the prepared composites are measured from 10 MHz to 1 GHz. Based on the experimental results, its application as electromagnetic (EM) materials is discussed.
