Dielectric properties of polystyrene mica composites

الملخص EN

The AC-electrical properties of polystyrene / mica composite were studied by using the impedance measurements technique.

The study was carried out as a function of frequency (three different values of frequency: 300Hz, 1 KHz and 10 KHz), and mica concentration (5, 10, 15.

30, 50 and 70 wt.

%).

It was found that the ac-conductivity and the dielectric behavior (constant and loss) are increased with incraased the mica concentration, while the ac-conductivity is increased wilh increasing frequency.
