The results of the study of morphology and photoluminescent properties of composites of polyvinylidene fluoride (PVDF) and europium complex ЕuR29 are reported. The increase of the concentration of ЕuR29 in PVDF has been found to cause the morphology change in the structural elements on the surface. It is shown that at high concentrations of ЕuR29 the refinement of the structural elements of the composition occurs. The study of photoluminescent properties of the composition PVDF+EuR29 confirms that with the increase of the concentration of ЕuR29 new maxima appear at the wave lengths 492, 502, 533 nm, linked with the europium complex under study in the present work.

New nanocomposite structures on the base of isotactic polypropylene and nanoparticles of zirconium dioxide have been developed. The distribution of nanoparticles of zirconium dioxide have been studied by optical microscopy (Motic AE 30/31) and scanning electron microscopy (SEM, Carl Zeiss). It is demonstrated that even on the first stage of mixing components the direct introduction of nano powder into the polymeric matrix produces clusterlike fractal dendrite structures. Electron microscopy study of the investigated samples shows that the developed technology of nanocomposite preparation allows for homogenous dispersion of the zirconium dioxide nanoparticles in the polypropylene matrix. Dielectric properties of the developed and prepared nanocomposites have been analyzed. It has been found out that in PP+ZrO2 nanocomposites a change of a dielectric permittivity, depending on frequency, is due to low-frequency polarization.

In this work, we describe the results of studying the effect of the temperature-time modes of crystallization on the structure and properties of nanocomposites based on polypropylene and cadmium sulfide prepared via electrical discharge treatment in an air medium above the breakdown strength of the air. The temperature-time modes of the crystallization and other treatment factors change the supramolecular structure of the polymer, the interfacial interactions between the components of the composites, and the thickness of the interfacial layer.

In this work is given results of influence of temperature and time regimes of crystallization on the structures and properties nanocompositions on the basis of polypropylene and cadmium sulphide, prepared from polymer, treated by electrical discharge in air quality. Has been shown temperature and time of crystallization and other technological regimes change supramolecular structure of the polymer, interphase interactions between components of compositions and thickness of interphase layer.

In present work has been investigated the in fluence of electrothermopolarization on the strength and photoluminescent properties nanocompositions on the basis of cadmium sulphide and polypropylene, which treated by elecrtical discharge in air quality. Has been shown that after electrothermopolarization amplitude of maximum increases at length of the waves λ=534 nm, λ=627 nm and λ=809 nm for nanocomposition PP+CdS. Electrothermopolarization changes phase interactions, in nanoparticles CdS are actuated additional luminescent centres, as a result amplitude of photoluminescence grows. Has been established that discharge treatment of polymeric powder, electrotermopolarization and other technological factors change su-pramolecular structure of the polymer, interphase interaction between components of the compositions and thickness interphase layer.
