The influence of external factors (heat treatment, high pressure) on the optical properties of the samples was analyzed. It was established that samples of pure PTFE4 after the specified external influence increase their throughput, while the largest increase in throughput is observed for samples that were obtained under high pressure, and for samples that were subjected to heat treatment during synthesis, an increase in throughput is characteristic ability with increasing synthesis temperature. For PTFE-4 composites from 5 wt. % CNT (film thickness h=200 μm) samples become opaque in the wavelength range λ=320-1000 nm and regardless of the method of their production, which indicates the possibility of using such materials as absorbing coatings.

The electrical and mechanical properties of nanocomposites based on carbon nanostructures has been studied. It is sown that a t a concentration of carbon nanotubes of 15-30 wt. %, the electrical resistance of the samples decreases to 1 order, while its mechanical properties change insignificantly, which is due to the transfer of free electrons from the metal to the CNT, which is comparable to the number of electrical contacts between the constituent elements of the composite and the competition between the numbers of tu nneling and ohmic contacts.
