Abstract: Experiment on neutron reflectometry is modeled during the study of the structural organization of fullerence nanoparticles in a thin film of a polymer nanocomposite. Several physically based models of structural organization of the nanoparticles in polymer matrix are considered in particular the uniform distribution, dense substrate layer, a layer on the surface of a polymer. The calculations show that it is possible to apply neutron reflectometry for clarifying the structural organization of nanoparticles in the nanocomposites with the mass concentration of fullerenes exceeding 1 %.

Keywords: neutron reflectometry, thin films, polymer nanocomposites, fullerenes.
