Abstract
The temperature dependence of the electrical resistivity (ρ) and current-voltage characteristics of composite films based on multi-walled carbon nanotubes and a 95/5 wt % polymer have been investigated in the temperature range of 300–450 K. An unstable behavior of the composite film structure upon cyclic heating has been observed. It has been found that the resistivity ρ has maxima at T ≈ 340 and ≈420 K, which are responsible for intrinsic defects. The current-voltage characteristics have been studied in the stationary and pulsed modes at different temperatures. They prove to be purely linear and correlate with temperature variations in ρ.
