Electrorheological Source of Nonlinear Dielectric Effects in Molecular Glass-Forming Liquids.

We have measured the dielectric relaxation spectra of eight glass-forming liquids in the presence of electric direct current (dc)-bias fields ranging from 100 to 500 kV/cm. For every sample, we observe two distinct field-induced effects: a reduction in the relaxation amplitude and an increase in the primary structural relaxation time that is associated with… CONTINUE READING
