Abstract
This paper presents the results of the dielectric
properties measurements conducted on Silica-Polypropylene
(PP) nanocomposites. According to prior investigations by
the authors silica nanoparticles have improved the
performance of the dielectric material considering
capacitor applications. Especially breakdown strengths
with ac and dc voltages and resistance against surface
degradation have increased. The relative permittivity and
dielectric losses have also been comparable to reference
PP. In this paper the results of the dielectric
measurements conducted on composites with 1-2 wt-% silica
are compared with reference PP. Silica dispersion in PP
was confirmed with transmission electron microscopy
(TEM). Weibull analysis was applied to the breakdown
strength measurement results with dc voltage. Capacitance
and loss factor measurements were conducted as a function
of temperature to study thermal behavior. The
measurements were conducted at the high voltage
laboratories of Tampere University of Technology and
Chalmers University of Technology. Statistical analysis
was applied to the results to determine the significance
of the differences between the materials. (26 refs.)
