Dielectric properties of epoxy resins with TiO2 nanofillers
Original language description
The paper deals with the dielectric properties of epoxy resins containing TiO2 nanofiller and with the potential use of dielectric spectroscopy for diagnostics of such nanocomposites. Epoxy nanocomposites are considered in the manufacturing of transformer stations and parts replacement, as their use may lead to smaller dimensions of the electrical apparatus. Both positive and negative features of TiO2 nanofillers in the epoxid are examined. The paper also deals with issues of operation time for these materials. This area is of great importance for practical application of epoxy nanocomposites, as the long-time stability of nanocomposites has not yet been established. Just on the contrary, the great number and surface area of interfaces between nanofiller particles and the epoxy matrix itself suggests a larger number of weak points and defect sources, which may contribute to a more rapid deterioration of nanocomposites as compared with classical composites without nanoparticles.
