Abstract: A structure aimed at modeling a polymeric nanocomposite loaded with
carbon nanotubes (CNTs) is simulated by considering, in a three-dimensional
space, a random distribution of impenetrable conducting cylinders inside an
insulating cubic matrix. The variation of the electrical conductivity of the
structure for different volume loadings of the conducting phase is estimated
through a 3D resistor network. The tunneling effect between conducting clusters
which is deemed responsible of the global conductivity is taken into account.
By using a Monte Carlo method, the electrical conductivity and the percolation
thresholds of the obtained structures are analyzed as a function of geometrical
and physical influencing parameters.
