摘要

摘要利用聚苯胺n -丁磺酸盐(PANBUS)与聚亚胺的离子相互作用，制备了具有电化学活性的多层自掺杂聚苯胺薄膜。通过QCM分析，计算出PANBUS吸附的动力学常数和自由能分别为2.3/M·sec和-5.4 kcal/mol。制备的膜具有聚苯胺的特征循环伏安图，多层膜的EQCM研究表明，氧化还原过程中膜的质量变化与所用电解质的阳离子和阴离子无关。

Electrochemical Quartz Crystal Microbalance Study of the Self-assembled Multilayered Poly(aniline N-Butansulfonate) Film

Abstract Electrochemically active multilayers of self doped polyaniline films were prepared by the ionic interaction between poly(aniline N-butanesulfonate) (PANBUS) and polyethylene imine. Kinetic constant and free energy of the PANBUS adsorption were calculated to be 2.3/M·sec and -5.4 kcal/mole, respectively from the analysis of QCM. The prepared film showed the characteristic cyclic voltammogram of polyaniline and EQCM study of the multilayered film indicated that the mass change during oxidation and reduction was independent on the cations and anions of the used electrolytes.
