This paper presents methods of obtaining film structures based on polyvinyl alcohol, polymethylmethacrylate with multi-walled carbon nanotubes on various substrates by pulling out of solution and drying with subsequent application of metal contacts. Test samples of polymer film structures with carbon nanotubes with curing in strong electric and magnetic fields for the orientation of with multi-walled carbon nanotubes in the polymer were prepared. The topography of the film surface was studied by atomic force microscopy. By treating nanotubes in a solution of iron chloride (III) and NaOH in diethylene glycol, their magnetic susceptibility is significantly increased, which makes it possible to equalize such "magnetic" carbon nanotubes in the polymer in magnetic fields with an induction of less than 0,5 T. The volt-ampere, C-V and noise characteristics of film structures at temperatures from – 60 ° C to 100 ° C and pressures up to 2 MPa were studied.
Key words: nanocomposites / carbon nanotubes / modification / orientation in a magnetic field / topology / electrical properties
