本文研究了外加磁场对苯胺电聚合过程的影响.在H_2SO_4介质中,当磁场方向垂直电极表面时,在0.58T处聚合速度最大,约为无磁场影响下的2倍;当磁场方向平行电极表面时,随磁场强度的增加聚合速度也增大,在0.7T时约为无磁场影响下的2.4倍;膜的成核生长是在动力学控制下的二维瞬时成核过程.此外,在HCl、HClO_4、HBF_4介质中,也观察到磁场的增强现象.
In this paper, the effect of applied magnetic field on aniline polymerization was studied. In H_2SO_4 medium, when the direction of the magnetic field is perpendicular to the surface of the electrode, the polymerization rate at 0.58T is the maximum, about twice that under the effect of no magnetic field. When the direction of the magnetic field is parallel to the surface of the electrode, the polymerization rate increases with increasing magnetic field , Which is about 2.4 times that of the non-magnetic field at 0.7T. The nucleation and growth of the film is a two-dimensional transient nucleation process under the control of the kinetics. In addition, magnetic field enhancement was also observed in HCl, HClO_4 and HBF_4 media.
