Structural Transformations in the Composite Films of Polyvinyl Chloride and Nanoglobular Carbon under Laser Irradiation

Resumo

Transmission electron microscopy and X-ray energy dispersive microanalysis have been used to study structural and chemical transformations occurring in polyvinyl chloride films containing embedded nanoglobular carbon particles after intense laser irradiation. It was established that irradiation led to the conversion of nanoglobular carbon into carbon nanocapsules with sizes of 5–10 nm. The chemical composition of the composite film samples changed after laser irradiation. Thus, the average concentration of chlorine decreased from 35 to 3 wt %, and the carbon content increased by 20–30 wt %. The possibility of obtaining carbon–carbon nanocomposite film materials with carbon nanocapsules embedded in an amorphous carbon matrix was demonstrated.
