Dielectric properties of ionomers at microwave frequencies

Abstract

Ionic polymers (ionomers) with interesting characteristics are emerging as important commercial polymers. Ionomers have the unique ability to behave as cross-linked materials at ambient temperatures and to melt and flow at elevated temperatures like thermoplastics. The complex permittivity and conductivity of a class of ionomers at microwave frequencies are determined using the cavity perturbation technique and the results are presented. D

Microwave Conductivity of Fe and Mg Based Nanocomposites

“…are complex quantities with real parts expressing the energy storage and imaginary parts expressing the energy dissipation in the material's medium. Finally, the electrical conductivity can be related to the imaginary part of the relative dielectric constant as [4]:…”

Frequency independent‐dependent conductivity and dielectric properties of some ionomers

“…Ionic polymers or ionomers basically contain a small percentage of ionic groups attached to a hydrocarbon backbone. The ionic interaction between the groups results in significant changes in polymer properties 1–3. The development of polymeric systems with ionic conductivity is one objective in polymer research 4.…”
