The Investigation of Glass Spheres Containing Elastomer Based Materials for Tunable Device Applications

Abstract

In this work, dielectric and tunability properties of glass spheres containing elastomer based materials have been investigated with dielectric spectroscopy as a function of frequency, composition and DC bias field. Real and imaginary part of dielectric constant and dielectric loss values of the gs1 (glass spheres), gs2, and gs3 were investigated in the frequency range of 100 to 40 × 10 6 Hz. Dielectric tunabilities of 69%, 87% and 33% were measured on gs1, gs2, and gs3 at 10 kHz and at room temperature. The degrees of anharmonic contributions to the polar ization are very high for gs2 and gs3 as 4.53 × 10 −8 and 1.77 × 10 −8 (mm/kV) 2 . Also, dielectric constant, FOM (%) and absorption coefficient a values were calculated at 10 × 10 3 Hz and 20 × 10 3 V/mm depending for different glass spheres.

Influence of Grafting of a Polymeric Antistatic Membrane Doped with Orthophosphoric Acid on its Electrical Properties

“…For PVC/SBR membranes doped with OPA it follows that the CBH model as the exponent s decreases as a function of temperature (45 and 55 wt %). For membranes of 30 wt %, it obeys a quantum mechanical tunneling (QMT) model as the s exponent increases with the temperature 41.…”
