The effect of a magnetic field on the polymerization process and the electrophysical characteristics of polyvinyl alcohol (PVA) films with the inclusion of multiwalled carbon nanotubes (MWCNTs) was studied. Using SEM micrographs, it was shown that the films obtained under the action of a magnetic field have a more homogeneous structure, while a significant number of MCNT agglomerations are present in the control samples. In the study of the conductivity at direct and alternating current, it was found that the films obtained in a magnetic field have a conductivity that significantly exceeds the conductivity of the control samples. It has been shown that the use of a magnetic field during polymerization has a noticeable effect on the properties and characteristics of nanocomposite films based on PVA and MWCNTs.
