Abstract
Polyurethane/CdS nanocomposite films were prepared by a solution mixing method. The surface morphological and electrical properties of PU/CdS nanocomposite films were investigated by characterization techniques such as scanning electron microscopy (SEM) and thermally stimulated discharge current (TSDC). The SEM images show the dispersion of CdS nanoparticles in PU matrix. In order to observe the effect of nanofillers in electret state, charge relaxation, and charge storage properties of nanocomposites, TSDC is employed to understand the mechanism of charge storage. TSDC data are an evidence of different types of relaxation process. The activation energy, released charge, and charge carrier mobility decrease while relaxation time and peak current increase with CdS nanoparticles concentration.
