Abstract
In present work has been investigated the influence of phase interactions in formation of photoluminescent and dielectric properties of polymeric nanocomposites on the basis PP + CdS. Has been shown that the increasing of concentration of initial solutions leads to adhesion of CdS nanoparticles i.e. with increasing of concentration the more Cd2+ and S2- ions are not used on formation of new germs, but ones are used on coagulation of initial particles. It is supposed when the sizes of nanoparticles are commensurable with supermolecular formation, then polymeric macromolecules effectively excite new additional luminescent centers by light influense. It is also shown that boundary phase interactions in polymeric nanocomposites PP+CdS plays important role on formation of its photoluminiscent properties. It means that it is possible to adjust photoluminiscent properties not only by component and its geometrical parameters matching, but also by impact on conditions of boundary and interphase effects.
