Abstract

In the current paper, Hui-Shia model for composite’s modulus is simplified and advanced to evaluate the electrical conductivity of carbon nanotubes (CNT)-reinforced nanocomposites (PCNT) by CNT aspect ratio, CNT network part, interphase district and tunnels between adjacent CNT. CNT loading, CNT magnitude and interphase depth suggest the proportion of networked CNT. In addition, CNT and tunneling intrinsic resistances express the entire conductivity of included components in nanocomposites. The reasonable roles of all factors in the conductivity and the proper matching between trial data and predictions approve the established model. Both dense interphase and long CNT improve the conductivity; however, reedy interphase or short CNT induces an insulated sample. The polymer tunneling resistivity negatively affects the conductivity, while CNT conductivity is an unsuccessful term. Furthermore, both short and wide tunnels desirably control the nanocomposite’s conductivity. © 2021, The Polymer Society, Taipei.
