The electret effect in poly-epoxypropylcarbazole

The regularities of dark discharge in ionic contact mode and of thermoelectret effect as well as the plastifying influence of some solvents on these effects have been investigated for layers of poly-epoxypropylcarbazole (PEPCa) and of its complexes with trinitrofluorenone (TNF). Frequency-temperature dependences of dielectric spectra have been analysed for layers and for high-concentrated solutions of PEPCa in dioxane and methylene chloride, too.
