Effects of additional amount of carbon micro-coils on the dielectric properties of its composite sheet

Abstract

The morphology and dielectric properties of carbon micro-coils (CMC) composite sheet were examined. Frequency dependence of dielectric parameters; dielectric loss angle (θ), dielectric loss tangent (tanδ) and relative dielectric constant (ε r ) were measured on single and double-helix composite sheet. It was found that these parameters of CMC/polysilicone composites extensively changed with the additional amount of CMC with polysilicone resine. It was also observed that the higher additional amount (wt%) of CMC is appropriate for high response.
