Producing carbon-carbon layers by laser irradiation of a polyvinyl chloride film containing carbon nanoparticles additives

Abstract

The possibility of using laser radiation for carrying out structural transformations in polyvinyl chloride films modified
by additions of nanoglobular carbon with diameter of particles 50–70 nm is shown. Under the influence of laser radiation is
observed ordering of graphene layers of carbon globules by the formation of nanocapsules with a diameter of 5–20 nm. At the same time, carbon is enriched in the polymer phase due to the dehydrochlorination of polyvinyl chloride. The results of scanning electron microscopy and energy dispersive spectroscopy indicate that these structural transformations occur only in the nearsurface region of a film not more than a few microns thick, with the formation of composite structures in which conglomerates of carbon nanocapsules are embedded in an amorphous carbon matrix. Interest in such materials is due to the fact that they combine the useful properties of the carbon matrix with a unique complex of electrophysical and optical properties characteristic for carbon nanoparticle.
