In the given work have been investigated influence of structure and charging condition on strength properties of nanocompositions, made on the basis of polypropylene and nanoclays Dk2 . It is shown that the addition of nanoclay Dk2 in polypropylene polymer increases concentration of the centers of localization of electric charges, i.e. on border of division of polymer and nanoclay are formed interphase layers which can play traps for charges, therefore the density and stability of electret charges can increase. Changes of inter- phase interaction and a thickness of a frontier layer can affect on strength properties of nanocompositions.
