| Abstract | ||||
| Space charge formation in a nano-composite thin film under dc stress at various temperatures was observed using the pulsed electro-acoustic (PEA) method. The Polyvinyl Chloride (PVC) /(Clay, Fumed Silica, and ZnO) nano-composite materials, which are made of Polyvinyl Chloride (PVC) mixed with each one of Clay, Fumed Silica, and ZnO nano-size filler, have changed their electrical properties than that in pure Polyvinyl Chloride. Therefore, the materiasls are expected to be used with smaller thickness as an insulator in the same dc applications. However, it is necessary to study the space charge characteristics, therefore, we tried to investigate the space charge formation in thin film of Polyvinyl Chloride (PVC) / (Clay, Fumed Silica, and ZnO) nano-composite materials under dc electric field at various concentrations of nanofillers and dc voltages using PEA system. From the experimental results, it was found that the space charge formation was strongly affected by the Clay, Fumed Silica, and ZnO contents in their nano-composites. | ||||
