Abstract

The aniline electropolyinerization under the magnetic field was studied by cyclicvoltammetry and potentiostatic step techniques. Theinaximum peak current was obtained at 0. 58 Twhen the magnetic flux was perpendicular to the surface of the working electrede in H_2SO_4 solution.These were speculated in terins of magnetic dircctional effect. But when the magneic flux directed inparallcl with the surface of elcctrode, the peak current obviously increased as the magnetic flux densityrised. The results uere explained as the enhancement of mass transfer by magnetohydredynamic(MHD) mechanism. The PAN film growth via a two-dimentional (2-D) instantaneous nucleationunder the electron transfer kinetic controlled. The enhanced effects were also obtained in HCl、 HClO_4、HBF_4 solutions.
