This work deals with the study of epoxy composites containing Si/SiO2 core/shell nanoparticles for insulation applications. Neat epoxy and epoxy based samples filled with micro and/or nanometric Si/SiO2 core/shell particles were characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), dielectric spectroscopy, dynamic mechanical analysis (DMA) as well as erosion...
Whether the surface resistance to erosion of a polymer nanocomposite system containing a conductive phase could be affected is the topic of this contribution. In order to answer this question, two material systems were fabricated and studied. Low-density polyethylene (LDPE) was prepared using ball-milling with Graphene Oxide (GO) up to 0.3 wt%. Epoxy resin was mixed with Carbon Black (CB) up to a...
It has been shown that epoxy resins modified with Glycidyl Polyhedral Oligomeric Silsesquioxanes (GPOSS) in contents of up to 20 wt% have enhanced ACBD strengths, resistance against corona discharges, as well as enhanced thermal conductivities and low dielectric losses, with the addition of 2.5 wt% of GPOSS in epoxy seeming to be an optimal value in terms of dielectric strength and losses. Furthermore,...
