Abstract:
Poly(vinylidene fluoride) based composites filled with semiconducting beta silicon carbide (beta-SiC) nanoparticles were prepared by means of solution mixing method. The dielectric responses of PVDF/beta-SiC nanocomposites over a wide frequency range were investigated. The results showed that the permittivity of composites increases with increasing filler content. A large permittivity of 610 together with a low loss tangent of 1.0 was achieved in the PVDF/SiC 50 wt% system. The composites exhibit dielectric relaxation process in the tested frequency range and such relaxation can be well described by the Cole-Cole equation.
