本文通过红外光谱、元素分析和循环伏安法,论述了聚苯胺经数次还原和氧化循环后对其组成、电极电位的稳定性以及电池的再充电性能的影响。在+0.260V至-0.234V(相对于SCE)之间,聚苯胺经数次还原和氧化循环后,氟和硼的含量(聚苯胺被再次氧化到+0.260 V)分别由13.4%和3.15%下降到1.61%和1.75%,红外光谱中BF_4~-的吸收峰消失;但是,循环伏安的电流-电压曲线、电极电位的稳定性及电池的再充电性能均未受影响,这是由于聚苯胺的母体未变。所以,聚苯胺的电化学性质主要决定于其母体。
The effects of polyaniline on the composition, electrode potential stability and battery recharging performance after several reduction and oxidation cycles were discussed by IR, elemental analysis and cyclic voltammetry. After several reductions and oxidation cycles of polyaniline between +0.260 V and -0.234 V (vs. SCE), the fluorine and boron content (polyaniline was reoxidized to +0.260 V) was increased from 13.4% and 3.15%, respectively, To 1.61% and 1.75% respectively. However, the absorption peak of BF_4 ~ - disappeared in the infrared spectrum. However, the current-voltage curve, the stability of the electrode potential and the recharge performance of the battery were not affected by the cyclic voltammetry. Aniline mother unchanged. Therefore, the electrochemical properties of polyaniline mainly depends on its parent.
