Preparation and Study of some Electrical Properties of PVA-Ni(NO<sub>3</sub>)<sub>2</sub> Composites

Abstract: The aim of this paper is to prepare and study the (D.C.) electrical conductivity of (PVA-Ni (NO3)2) composites at different temperatures. For that purpose, PVA films with Ni (NO3)2 salt additive were prepared with different concentrations‎ 2, 4, 6, 8 and 10 wt. % and with thickness of 45μm by using casting technique. The experimental results for PVA-Ni (NO3)2) ‎films show that the (D.C.) electrical‏ ‏conductivity increased with increasing ‎the filler content and the‏ ‏temperature, and the activation energy was… Show more

“…The advantage of the absorption coefficient to conclude the transition electrons nature, when the value of absorption coefficient is high in the higher energy expected direct transition of electrons. A conservation of momentum and energy can be accomplished before photons and electrons , where the absorption coefficient amount is depressed and the predicted indirect transfer to electrons [33]. A conservation of momentum is through phonons alone.…”
