Dielectrical insulation of polyvinyl alcohol, ethylene glycol and crushed pomegranate peel (PVA-EG-PP)‎ composite materials

Abstract EN

Samples are prepared from mixture of manufacture foam materialpolyvinyl alcohol with ethylene glycol (PVA-EG) and additive of crushed andsieved pomegranate peel (PP).

Crushed pomegranate peel (PP) and the mixture arediagnosed by Fourier transforms infrared (FTIR) spectrophotometer.

The electricalinsulation parameters are measured.

The dielectric parameters such as dielectricconstant (ɛ′), dielectric loss factor (ɛ′′), free space capacitance (Co), conductance(Gs), dependent conductivity (σac), and independent conductivity (σdc) havebeen investigation.

There is a significant decrease in dielectric loss factor ε′′ to2.39 as the grain sizes of crushed and sieved (PP) increased to (600) μm sample(4), and various recent investigations of functionalization of PP fillers to improvecompatibility with polymers.

The electrical conductivities of composites are foundto increase at sample (2) and (3) PP grain size (212) μm and (300) μm and decreaseat sample (4).
