✦ Synopsis

Surface modification of the silicon carbide nanoparticles (SiC P ) by electroless nickel plating was performed. The XRD, TEM and XPS results showed that a nanoscale agglomerative nickel layer was coated on the SiC P . Dielectric permittivities of the original SiC P and nickel-coated SiC P were measured respectively in the GHz frequency range from 8 to 12 GHz. The real part and dielectric loss tangent of the nickel-coated SiC P were significantly enhanced. The origin of the enhancement was discussed in theory, and also explained by discussing practical influence factors.
