Fullerene is likely to form aggregates so that it is diificult to disperse it well in a polymer matrix, and few reports have been made on electrical insulation properties of fullerene filled composite as electrical insulating material. This paper deals with fullerene dispersion method in conventional epoxy resin (EP) and breakdown strength (BDS) of the composite with different filler loading of fullerene...
Multi-walled carbon nanotube/epoxy resin (MWCNT/EP) composites with filler contents from 0.03wt% to 0.5wt.% and two different aspect ratios are prepared by solution blended process. Carbon nanotubes are dispersed by sonication and high speed shear force. The impact of aspect ratio on electric and thermal conductivity of nanocomposites has been studied. Experiment results illustrate that percolation...
In this paper, we investigate the influence of nanofiller material and its concentration on dielectric properties of epoxy-based composite systems. A comparative study is performed between the unfilled base epoxy, the systems containing one type of nanoparticles (silicon dioxide, aluminum oxide or aluminum nitride) and composites containing a combination of two different fillers inside the host polymer.
For the application of nanocomposite materials to solid insulator in electric power apparatus, we investigated the influence of the dispersibility of nanoparticles on dielectric property. Experiments were carried out in epoxy/alumina nanocomposites with the particle dispersion techniques using ultrasonic wave and centrifugal force. As the result, we verified the specific characteristics of dielectric...
