Abstract: Effect of regimes of fabrication of nanostructured polymer composites filled with carbon nanotubes on electrophysical characteristics is analyzed. Dependence of the conductivity of composites in a frequency interval of 50 Hz–5 MHz and a temperature interval of 15–375 K on the dimensional effect of multi-walled carbon nanotubes, method for functionalization, and method for ultrasonic processing is studied. It is shown that different effects of electric transport in composites affect the resulting conductivity. The best electrophysical parameters are obtained with the aid of noncovalent functionalization of nanotubes and focused ultrasound treatment. The method makes it possible to obtain a composite conductivity of 0.01 S/сm in the specified frequency interval at a filler concentration of 0.5 wt.%.
Keywords: multi-walled carbon nanotubes, epoxy polymer, composite material, electrical conductivity.
