Article Synopsis
- Five types of nanofillers (silica, surface-silylated silica, alumina, surface-silylated alumina, and boron nitride) were tested in epoxy/amine resin nanocomposites to assess their dielectric properties, focusing on the effects of nanoparticle surface functionalization and water absorption.
- The research found that water absorption significantly impacted the insulating properties of the materials, with interfacial polarization increasing while the dielectric strength decreased, particularly in composites with silica.
- Among the tested composites, those with silylated alumina and boron nitride demonstrated the best dielectric performance, highlighting the importance of surface interactions with water.
Mica/Epoxy-Composites in the Electrical Industry: Applications, Composites for Insulation, and Investigations on Failure Mechanisms for Prospective Optimizations.

Chair of Polymer Chemistry, Montan University Leoben, Otto-Glöckl-Strasse 2, Leoben 8700, Austria.
The investigation of mica and mica/epoxy-composites has always been of high importance and has gained increased attention in recent years due to their significant role as insulation material in the electrical industry. Electrical insulation represents a key factor regarding the reliability and lifespan of high voltage rotating machines. As the demand for generating power plants is increasing, rotating machines are of intrinsic importance to the electrical energy supply.

The copoly(2-oxazoline) pNonOx80 -stat-pDc(=) Ox20 can be synthesized from the cationic ring-opening copolymerization of 2-nonyl-2-oxazoline NonOx and 2-dec-9'-enyl-2-oxazoline Dc(=) Ox in the ionic liquid n-hexyl methylimidazolium tetrafluoroborate under microwave irradiation in 250 g/batch quantities. The polymer precipitates upon cooling, enabling easy recovery of the polymer and the ionic liquid. Both monomers can be obtained from fatty acids from renewable resources.
