A plasma-polymerized tetrafluoroethylene film has dielectric loss peaks below -50°C and approximately at 40°C. The effects of the substrate temperature during polymerization and of plasma irradiation after polymerization on the appearance of the peaks were studied. the low-temperature peak seems to be due to local-mode relaxation of polar groups, while the high-temperature peak seems to be due to phase transition.
