Синтезированы пленочные образцы сополимера поли(винилиденфторид-трифторэтилена) с добавлением 2 % углеродных нанотрубок. Определены температуры сегнетоэлектрического фазового перехода и значения диэлектрической проницаемости образцов на частоте 1 МГц. Методами сканирующей зондовой микроскопии визуализирована поверхность, получены значения эффективного пьезоэлектрического коэффициента. Показано, что включение углеродных нанотрубок в полимерную матрицу повышает значения диэлектрической проницаемости и пьезокоэффициента сополимера.

Film samples of poly(vinylidene fluoride-trifluoroethylene) added with 2% of carbon nanotubes are synthesized. The temperature of ferroelectric phase transition and dielectric permeability of the samples are determined at a frequency of 1 MHz. Surface morphology and piezoelectric constant of copolymer films are measured using scanning probe microscopy. It has been shown that the incorporation ofcarbon nanotubes into the polymer matrix increases the value of effective piezoelectric coefficient and dielectric constant of the copolymer poly(vinylidene fluoride-trifluoroethylene).
