Abstract

With the aim of creation of effective electret materials, the composite films, based on poly(vinylidenefluoride) (PVF), in addition with segnetoelectric of barium titanate (BaTiO3) were obtained in concentrationrange of 0.5 – 5.0 %vol. It is established, that presence of BaTiO3, at low content of, leads to increase ofcrystallinity degree, and, practically, have no influence on, when at content of 1.0 – 5.0 % vol. of. There arePVF’s melting temperature range becomes narrower, when at 0.5 – 1.0 % vol. of, and, this pointing on morehomogeneous crystallite formation by dimensions in. When at high content (5.0 % vol.) of BaTiO3, there isdecrease of crystallization temperature observed (at 5 ºC), and then, there is temperature range broadening exists,and this pointing on forming of larger, but less homogeneous crystallites by dimensions in. It is determined, whenin composite films of PVF - BaTiO3 , that surface charge is more stable at BaTiO3 content of 4.0 %vol. in, andthen, one reaches value of 10-6 Cl/m2, when at conditions of treatment with electric field and crown discharge,and, at film charge value of 500 kV/m in. There are non-linear dependence of dielectrical permittivity exists,either when at low, or very high frequencies, and this may be linked with influence of high-disperse addition onpolymer’s crystalline structure formation, and sub-surface layers of one.
