摘要：
Dynamic dielectric measurements were carried out for Langmuir-Blodgett films based on vinylidene fluoride with trifluoroethylene copolymers P(VDF/TrFE). Debye-type dielectric relaxation has been revealed for all films of different composition and thickness. The values of the relaxation time and the damping coefficient depend on the film thickness. Frequency and temperature dependences of conductivity have been investigated.
