Study of dielectric and insulation properties of nano-additives doped epoxy resin

This paper aims to reveal the high voltage insulation and dielectric properties of epoxy resin samples with various nano-particle of Al₂O₃ and SiO₂. In addition, experimental results were measured for dielectric properties (permittivity and tanδ at 1 kHz and 10 kHz), breakdown voltage and dielectric strength. The dielectric and high voltage insulation properties of nano-composites are analyzed in detail with respect to different experimental parameters such as frequency, particle size of additives, additive contents, additive permittivity and thickness of the samples. The results show the effects of nano-additives in permittivity, dissipation factor, breakdown strength and voltage for nano-composites.
