Abstract

The research of microstructure and electric properties of the systems based on polyethylene oxide and carbon nanotubes, prepared by different methods is done using the methods of impedance spectro scopy and optical microscopy. It is set that the probed systems show the percolation behavior. It is discovered that using the method of ultrasonication in melt, the threshold of electric percolation is 0,4 %, and for the system, prepared by the method of ultrasonication in polymer solution — 0,52 %. It is set that in the system, prepared by the method of ultrasonication in polymer solution, the lar ge aggregates of nanotubes was formed via the long time of solvent evaporation. The method of ultra sonication in melt is the most perspective for preparation of polymer nanocomposites with low percolation threshold.
