Effect of low amount of nanosilica on dielectric properties of polypropylene
Abstract
This paper presents the results of the dielectricproperties measurements conducted on Silica-Polypropylene(PP) nanocomposites. According to prior investigations bythe authors silica nanoparticles have improved theperformance of the dielectric material consideringcapacitor applications. Especially breakdown strengthswith ac and dc voltages and resistance against surfacedegradation have increased. The relative permittivity anddielectric losses have also been comparable to referencePP. In this paper the results of the dielectricmeasurements conducted on composites with 1-2 wt-% silicaare compared with reference PP. Silica dispersion in PPwas confirmed with transmission electron microscopy(TEM). Weibull analysis was applied to the breakdownstrength measurement results with dc voltage. Capacitanceand loss factor measurements were conducted as a functionof temperature to study thermal behavior. Themeasurements were conducted at the high voltagelaboratories of Tampere University of Technology andChalmers University of Technology. Statistical analysiswas applied to the results to determine the significanceof the differences between the materials. (26 refs.)
