Abstract

The aniline electropolyinerization under the magnetic field was studied by cyclic voltammetry and potentiostatic step techniques. The maximum peak current was obtained at 0.58 T when the magnetic flux was perpendicular to the surface of the working electrode in H₂SO₄ solution. These were speculated in terins of magnetic dircctional effect. But when the magneic flux directed inparallcl with the surface of elctrode, the peak current obviously increased as the magnetic flux densityrised. The results were explained as the enhancement of mass transfer by magnetohydredynamic (MHD) mechanism. The PAN film growth via a two-dimentional (2-D) instantaneous nucleation under the electron transfer kinetic controlled. The enhanced effects were also obtained in HCl, HClO₄, HBF₄ solutions.
