- Abstract
Isothermal polarization and depolarization currents in polystyrene doped with DR1 chromophore molecules have been measured and analyzed in order to study the electrical relaxation of the poled order in this guest-host system. It has been shown that the superposition principle is applicable to the doped polystyrene at temperatures lower than the glass transition temperature indicating that the polymer system under study can be considered electrically as a linear one with a negligible electric conductivity. The response function was not exponential one, but characterized by a broad distribution of relaxation times.
