采用电势阶跃法，在圆柱形扩散体系下，测量了不同电流密度下制备的聚苯胺中BF4-离子在非掺杂过程中的扩散系数。在不同电流密度下，在HbF4水溶液中制备的聚苯胺均为纤维状结构，但其直径不同。从电势阶跃实验的结果可以看出，随着聚苯胺直径的增大，去掺杂过程中聚苯胺中的扩散系数增大。另一方面，从傅里叶变换的红外光谱可以看出，它们具有非常相似的化学键特征
The diffusion coefficients of BF 4 - ion during the undoping process in polyanilines prepared at various electropolymerization current densities were measured by the potential step method, assuming the cylindrical diffusion system. All polyanilines prepared at various current densities in HBF 4 aqueous solution have a fibrous structure, but their diameters were different. From the result of the potential step experiment, it can be seen that the diffusion coefficients in these polyanilines during the undoping process increased with increasing diameter of polyaniline. On the other hand, from Fourier transformed infrared spectra, it can be seen that they have very similar chemical bond characteristics
