Abstract: The electrical properties of anisotropic carbon nanotubes (CNTs)/polycarbonate (PC)/
polyethylene (PE) (ACPC) strongly depended on the CNTs concentration. When the ACPC was
subjected to isothermal treatment (IT), the resistivity variation in both the parallel and
perpendicular directions had the characteristics of a relaxation as a function of temperature.
During the IT the orientation of the PC microfibrils was gradually damaged and CNTs/PC
microfibrils were deformed and changed to short fibers, leading to a transition from anisotropy
to isotropy. The velocity of the conductive network reconstruction could be characterized by the
relaxation time, and the resistivity of the composite during the IT process can be instantaneously
predicted based on the relaxation equation. The relaxation time and the equilibrium resistivity of
the composite during IT were determined by the IT temperature and CNT content. © 2013
