Engineering Physics Annotation << Back THE PHYSICAL MEANING OF REINFORCEMENT EFFICIENCY OF POLYMER NANOCOMPOSITES WITH 1D- AND 2D-NANOFILLERS L.B. ATLUKHANOVA, G.V. KOZLOV For description of elastic modulus of polymer nanocomposites, filled with 1D- and 2Dnanofillers (carbon nanotubes and graphene oxide, respectively), the modified mixtures rule, taking into consideration efficiency of reinforcement of polymers with the indicated nanofillers. It has been found that efficiency factor of nanofiller is linear function of ratio of volume contents of interfacial regions and nanofi ller independently of type of the last. The used technique of calculation of carbon nanotubes density was shown, that this parameter is lower substantially then assumed earlier. As one can see, the ratio of volume fractions of interfacial regions and nanofiller characterizes ability of the last to generate interfacial regions. The calculation of elastic modulus of nanocomposites in consideration according to the modifi ed mixtures rule was shown good (within the limits of 8 %) correspondence with experimental data. This assumes that nanofiller efficiency as reinforcing element of nanocomposites structure is defined by its ability to generate interfacial regions, but not by its initial characteristics. Key words: nanocomposite, carbon nanotubes, graphene oxide, mixtures rule, interfacial regions, loading efficiency. DOI: 10.25791/infizik.08.2019.808 Contacts: - Pp. 16-20.
