Abstract
The results of a study of the temperature and frequency dependences of the dielectric permeability and dielectric loss of PVDF + TlInS2 and PVDF + TlInS2 + Al composites at frequencies of 10–105 Hz and temperatures of 20–150°C and the effect of 50-nm aluminum nanoparticles on the dielectric properties of PVDF + x vol % TlInS2 composite materials are described. It is revealed that an increase in the percentage of the TlInS2 filler in the matrix leads to an increase in the dielectric permeability and dielectric loss of these materials. An increase in the amount of the PVDF + x vol % TlInS2 + y vol % Al composites is also observed with an increase in the aluminum nanoparticle content in the composite; this effect leads to a change in the Maxwell–Wagner space-charge polarization. Under the effect of aluminum nanoparticles, the pattern of the frequency dispersion of the dielectric loss of the studied composites changes significantly.
