Dielectric relaxation in energy condensed systems on the basis of polyefirretane elastomer. I. Frequency dependence

Аннотация

This paper describes the experimental study of dielectric relaxation in energy condensed systems based on ether urethane rubber plasticized by glycerin trinitrate and ammonium perchlorate, HMX, and aluminum powders in the frequency range of the electric field from 40 to 1.2 · 10⁹ Hz. Depending on the field frequency, it was possible to determine relaxation processes caused by dipole polarization, the bulk electrical conductivity of a polymer binder, and the influence of the surface of aluminum particles.
