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

The selected dielectric studies are presented of ionically conducting mater ials (liquid crystal, epoxide resin) in the range of time, 10(-4) to 10(4) s, or frequency, 10(-4) to 10(4) Hz. The properties of the space charge at the blocking electrodes were taking into account. Investigations were focus ed on the time domain dielectric response of the model liquid crystalline p entylcyanobiphenyl. Similar studies were performed also on the epoxide resi n Epidian 3. An influence of external parameters like temperature or concen tration of impurities were included to interpret the obtained results. This interpretation was established on the principles of the two theoretical mo dels for the space charge polarization.
