To reveal the regularities of the electrical conductivity of single-walled carbon nanotube (SWCNT) films under tension, a coarsegrained model of the film fragment with size of 200×60 nm and thick of 50 nm with randomly oriented tubes was constructed. Using the method of molecular dynamics, it was found that during the stretching process the average number of contacts between tubes decreases nonlinearly. The slower the stretching, the greater this value at maximum stretching. It is shown that stretching promotes the ordering of the tubes in the film. The dynamics of the film resistance under tension and its dependence on the stretching time was obtained by constructing the resistor network.
