Vol. 27, No. 4/2

1237--1242

The method of analysis and assessment of the results of investigations of nanofilled varnishes used for electrical insulation have been presented. The proposed method enabled consideration of an effect of the coating thickness. The investigation indicated that improving of the bond strength depends on loading and the size of nanoparticles. The method of fabrication of composites with nanoparticles has an influence on their properties. Composites with fumed silica showed improved dielectric properties. Absorption of water of all formulated varnishes with nanofillers decreases provided that some additives were incorporated.

Analysing and summary the results of investigations of nanofilled varnishes used for electrical insulation have been presented. The used method of analysis has enabled consideration of an effect of the thickness of coating. It was found that improving of the bond strength have depended on loading and the size of nanoparticles. A way of formulate of composites with nanoparticles impacted also on the properties. The versions with fumed silica have shoved improved dielectric properties. Water absorption of all formulated varnishes with nanofillers decreases provided that some additives were incorporated.
