“…Polyesterimide resin filled with nanosilica, montmorillonite and aluminium oxide in portions of 1.5 wt% were investigated in [54]. Thermoanalytical methods, breakdown measurements and partial discharge measurements showed that hydrophilic nanosilica as well as aluminium oxide presented the best results w.r.t.…”

Polymer nanocomposites constitute a new generation of insulating materials, capable of offering better electrical, thermal and mechanical properties. Past research indicated that such materials may replace conventional polymers for a variety of industrial high voltage applications. In the present paper, polymer nanocomposites are investigated regarding the insulation of enameled wires. Possible nanocomposite candidates are discussed.

“…Attempts to modify polyesterimide resin with nanoparticles with focus on the changes in their dielectric properties have been superficially described in the literature, especially when nanosilica [ 3 , 27 ], and occasionally other oxides such as ZnO, TiO

, or Al

[ 28 , 29 ] were incorporated to the neat resin. However, the main aim of this study is to provide new knowledge on the behavior of synthesized polymer NC materials based on a commercially used PEI with dispersed Al

and ZnO nanoparticles at the various frequencies and temperatures accompanied by other results such as from dynamic mechanical thermal analysis (DMA) or proton nuclear magnetic resonance (NMR).…”

The influence of various types of nanoparticle fillers with the same diameter of 20 nm were separately incorporated into a single component impregnating resin based on a polyesterimide (PEI) matrix and its subsequent changes in complex relative permittivity were studied. In this paper, nanoparticles of Al2O3 and ZnO were dispersed into PEI (with 0.5 and 1 wt.%) to prepare nanocomposite polymer. Dielectric frequency spectroscopy was used to measure the dependence of the real and imaginary parts of complex relative permittivity within the frequency range of 1 mHz to 1 MHz at a temperature range from +20 °C to +120 °C. The presence of weight concentration of nanoparticles in the PEI resin has an impact on the segmental dynamics of the polymer chain and changed the charge distribution in the given system. The changes detected in the 1H NMR spectra confirm that dispersed nanoparticles in PEI lead to the formation of loose structures, which results in higher polymer chain mobility. A shift of the local relaxation peaks, corresponding to the α-relaxation process, and higher mobility of the polymer chains in the spectra of imaginary permittivity of the investigated nanocomposites was observed.
