Fabrication and Electromagnetic Characteristics of Composites Containing Electroless Metal-coated Carbon Nanofibers

چکیده
To improve the electromagnetic characteristics of conductive nano fillers, carbon nanofibers (CNFs) with nickel-phosphorous (Ni-P) and nickeliron (Ni-Fe) have been fabricated by the electroless plating process. Observations by the electron microscopy (SEM/TEM) and element analyzer (EDS/ELLS) showed the uniform Ni-P and Ni-Fe coated CNFs. The compositions of the plating layers were about Ni-6wt%P and Ni-70wt%Fe, respectively. The average thicknesses of the plating layers were about 50 ~ 100 nm. Composites with various weight percentages (30, 50, 70 wt%) of fillers were fabricated. Composites containing Ni-Fe coated CNFs had higher dielectric and magnetic loss than Composites containing Ni-P coated CNFs.

Copper coated SiC powders having three different amounts of copper, in the range of 20-60 wt%, were prepared via electroless coating process. The produced composite powders were uniaxially cold compressed and sintered at different temperatures and times under protective atmosphere. It was found that composite Cu/SiC powders and a relatively dense copper matrix composite with a uniform distribut...
