We perform molecular dynamics simulations of a coarse-grained model ionomer melts in an applied oscillating electric field. The frequency-dependent conductivity and susceptibility are calculated directly from the current density polarization density, respectively. At high frequencies, we find peak real part due to plasma oscillations ions. lower dynamic response ionomers depends on ionic aggregate morphology system, which consists either percolated or isolated aggregates. show that field can be understood by comparison with relevant time scales systems, obtained independent calculations.
