Nanocomposite samples of the copolymer of ethylene and vinyl acetate containing carbon nanofibers and nanotubes have been prepared by mixing in solution. In order to improve interfacial interactions in the polymer-nanofiller system they were subjected to a preliminary chemical functionalization. The efficiency of functionalization was estimated by the IR spectroscopy. The X-ray diffraction and strength characteristics of the obtained nanocomposites filled by the untreated and functionalized carbon nanofibers and nanotubes with different filling degree were compared.

On the relationship between optical and structural properties of polymer films modified by carbon micro and nanopartciles

The studies were concentrated on investigations of optical and structural characteristics of polymeric films filled by carbon micro and nanoparticles. Light transmission in the region of visible spectra of the films based on gelatin and polyvinyl alcohol was found to be almost independent of the wavelength. Carbon particles appeared to have no intrinsic absorption bands within the UV region. In the case of aggregation, nanotubes start to form clusters with an optical fractal structure, while the films display spatial fluctuations in transparency accompanied by deviations from the Bourguer-Lambert-Beer law. In contrast to nanoparticles, microparticles reduce the roentgen level of crystallinity of the films.
