Effect of the Structure and Charge State on the Strength Properties of Nanocomposites Based on PP + D_(K2) Films

摘要

In this work, we study the effect of the structure and charge state on the strength properties of nanocomposites prepared on the basis of polypropylene (PP) and D_(k2) nanoclays. It is shown that the addition of the D_(k2) nanoclay into the PP polymer increases the concentration of the centers of localization of electric charges; that is, interfacial layers are formed at the polymer-nanoclay interface; they can play the role of a trap for charges; this results in an increase in the density and stability of the electret charges. A change in the interfacial interactions and the thickness of the boundary layer can have an effect on the strength properties of the nanocomposite.
