Polymer based nanocomposites may exhibit enhanced electrical insulating properties. If we add silica nanoparticles to polydimethylsiloxane, we can see in the high voltage arc resistance test that the silica nanoparticles improve the material behavior.
Our poster aims to identify the origin of the increased arc resistance in silica nanocomposites and the dependence on different parameters such as the silica-volume-fraction, the molecular mass of the polymer and in changing the modification of the nanoparticles.
We produce silica nanocomposites and by different measurements, e.g. SAXS and SANS, we characterize the microscopic behavior. From these results we want to find a model to describe the macroscopic behavior, i.e. the resistance to high voltage arcing.
