Temperature – Frequency Characteristics of Composites with Semiconductor Fillers

UDC 541.64:539.26:537.529

This paper presents the results of the investigation of the temperature and frequency dependence of the dielectric constant and the tangent of angle, of the dielectric loss of the composite materials – low-density polyethylene – with solid fillers: LDPE/CdS and LDPE/In₂Se₃ in the temperature range 300–450K and in the frequency range 0–10¹⁴ Hz. It was revealed that by varying the amount of fillers and the effects of external factors it is possible to get new composite materials with the required dielectric properties.

Keywords: CdS, In₂Se₃, low-density polyethylene, dielectric permittivity, dielectric loss, dielectric characteristics.
