“…Specifically, at a frequency of 100Hz, the values of Ɛ r for BaTiO 3 , TiO 2 , CaCO 3 , and Al 2 O 3 increase by 45%, 14%, 18%, and 16%, respectively. The observed reduction in space charge in the PVC matrix, as evidenced by the capturing behavior of ceramics, supports the findings of [16,40]. The primary current carriers were attributed to free ions generated from ingredients used in the polymerization reaction of PVC, such as the stabilizer, as well as ingredients in the plastifier itself.…”

Poly-Vinyl Chloride (PVC) is a commonly used material used in cable insulation sheaths, but its dielectric properties can be negatively impacted by electric aging. This study investigates the use of nano-fillers, specifically alumina (Al2O3), titanium dioxide (TiO2), calcium carbonate (CaCO3), and barium titanate (BaTiO), in order to improve the dielectric properties of PVC. Films of PVC were doped with nano-fillers and were then exposed to an alternating voltage of 15kV for various time periods (1, 2, and 3 hours). The dielectric properties of PVC were measured using an impedance analyzer, and the results indicated that the use of these nano-fillers had a positive effect on the dielectric characteristics of PVC.

Polyvinyl chloride (PVC) is widely used as insulator in electrical engineering especially as cable insulation sheaths. In order to improve the dielectric properties, polymers are mixed with ceramics. In this paper, PVC composites with different weight percentages 2 wt.%, 5 wt.%, 8 wt.% and 10 wt.% were prepared and investigated. Loss index ([Formula: see text]) and dielectric constant ([Formula: see text]) have been measured using an impedance analyzer RLC. Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) equipped with energy dispersive X-ray (EDX) have been used as characterization techniques. The incorporation of BaTiO3 does not modify the crystallinity and the morphology of the PVC but reduces the space charges, therefore the dielectric losses. The frequency response analysis has been followed in the frequency ranges (20–140 Hz and 115–1 MHz). Relaxation frequencies have been evaluated in each frequency range. Experimental measurements have been validated using Cole–Cole’s model. Experimental results show well that BaTiO3 as a filler improves the dielectric properties of PVC.
