The ac electrical conductivity and dielectric constant of perfluorotetradecanoic acid monohydrate (PFTDA) were investigated in the frequency range from 1 Hz to 1 MHz and the temperature range from 5 K to 300 K. At temperatures below 300 K, the ac conductivity and dielectric constant follow the universal dielectric response (UDR) typical of hopping or tunneling of localized charge carriers. The analysis of the temperature dependence of the UDR parameter s in terms of the theoretical model for small polarons revealed that below 300 K this mechanism governs the charge transport in PFTDA.
