Properties of polytetrafluoroethylene films modified with mono- and two-component titanium-phosphorus oxide systems by alternating treatment of the polymeric substrate in a prescribed order with vapors of reagents from the series TiCl4, PCl3, and H2O were examined. It was found that the energy characteristics of the sample surface with two-component oxide systems P–Ti and Ti–P in comparison with polytetrafluoroethylene modified with only phosphorus or titanium oxide functional groups due to the increase in the polar component of the surface energy. Specific features of the effect of stabilization of the electret charge in modified polytetrafluoroethylene films. It was shown that the best electret properties are possessed by titanium-containing polytetrafluoroethylene films, including those with two-component titanium-phosphorus oxide additives. According to the results of a differential-thermal analysis, modified samples exhibit an increased thermo-oxidative stability manifested in that the onset temperature of the polymer decomposition increases by 40–50° and the loss of mass decreases by 17–23% as compared with an unmodified sample at 650°C.
