Dielectric response of ionically conducting liquids in the low-frequency region

The selected dielectric studies are presented of ionically conducting materials (liquid crystal, epoxide resin) in the range of time, 10/sup -4/ to 10/sup 4/ s, or frequency, 10/sup -4/ to 10/sup 4/ Hz. The properties of the space charge at the blocking electrodes were taking into account. Investigations were focused on the time domain dielectric response of the model liquid crystalline pentylcyanobiphenyl. Similar studies were performed also on the epoxide resin Epidian 3. An influence of external parameters like temperature or concentration of impurities were included to interpret the obtained results. This interpretation was established on the principles of the two theoretical models for the space charge polarization.
