Electrophysical properties of gamma-irradiated polyethylene terephtalate (PETPh\CdS) nano-composits on the base of porous membranes		  pdf 

ABSTRACT

The electrophysical properties of initial and irradiated PETh/CdS nano-composites obtained on the base of industrial track membranes from PETPh with three and twenty of formation cycles are investigated in the present work. It is shown that the observable effects in frequency dependence of electrophysical properties of PETh/CdS composites are connected with polarization change in matrix interphase boundary with filler and CdS nano-particles in PETPh near-surface region and radiation processes in polymer matrix at influence of gamma radiation. The study of frequency dependence of resistivity of porous PETPh and composites on PETh/CdS base shows that the resistivity of porous PETPh decreases as a result of destruction after influence of gamma radiation and the taking place matching leads to the increase of physical interaction in boundary nano-particle – polymer, and resistivity of PETh/CdS composites relatively increases.

Keywords: Polyethylene terephthalate (PETPh), porous track membrane, dielectric constant, dielectric losses, resistivity, interphase boundary, layerwise chemisorption, irradiation dose.
