Abstract

In this article, a mechanics model for the modulus of nanocomposites is progressed for the electrical conductivity of polymer nanocomposites reinforced with carbon nanotubes (CNT), named as PCNT by CNT nets, interphase and tunneling districts. The extended CNT consider the interphase and tunneling areas, and the resistances of CNT, interphase and tunneling districts estimate the conductivity of prolonged CNT. The fine match between forecasts and empirical results for several examples as well as the consistent correlation of conductivity to all factors supports the predictability of the progressive model. The conductivity of nanocomposite systems directly depends on the network size and interphase depth, but the conductivities of CNT and interphase are unproductive. Additionally, low percolation onset and little polymer tunneling resistivity together with the wide and undersized tunnels beneficially improve the nanocomposite’s conductivity. © 2021, The Author(s), under exclusive licence to Societa Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature.
