Abstract: The effect of a magnetic field with an induction of 0.02 T on the electrooxidation of pyrrole is considered. Electropolymerization of pyrrole monomers was performed under potentiostatic conditions and by cyclic voltammetry using a gold rotating disk electrode. Morphology of the polypyrrole films was determined by scanning electron microscopy. The magnetic field was created by a permanent magnet located near the cell. The direction of the magnetic field vector was perpendicular to the electrode surface. It is shown that a magnetic field with a weak induction affects the electropolymerization of pyrrole. Indeed, the magnetic field changes the rate and the limiting stage of the pyrrole electropolymerization process. The limiting stage of the pyrrole electrooxidation under the influence of a magnetic field with a weak inductance has been determined. The surface morphology of polypyrrole obtained in a magnetic field (0.02 T) differs from the surface morphology obtained without the use of a magnetic field. [ABSTRACT FROM AUTHOR]
