Abstract

The dielectric dispersion of poly(vinylidene fluoride-trifluoroethylene) copolymer films prepared using the Langmuir-Blodgett technique is studied. All films of different composition and thickness undergo a Debye type dielectric relaxation. It is found that the relaxation time τ depends on the thickness of the film.
