The mixed conductivity behavior of polythiophene-based anionic and cationic polymers is studied under controlled atmospheres in this contribution. The conjugated polyelectrolytes are based on regioregular polythiophene backbones with either pendant sulfonate anions or imidazolium cations with counterbalancing tetrabutylammonium hexafluorophosphate and bromide anions, respectively. Direct current, four-point-probe measurements and impedance spectroscopy are performed to separate electronic and ionic conductivity. Optical absorption spectroscopy is used to make statements about the aggregation of the polymer chains and to visualize the electronic doping behavior. Similar to a pure conjugated polymer such as poly(3-hexylthiophene) the electronic conductivity can be tuned over a wide range from below 10⁻⁶ S/cm to 2.2 S/cm by external doping with the strong electron acceptor F₄TCNQ by sequential solution doping. The ionic conductivity on the other hand is shown to be strongly dependent on the degree of water uptake. We show that values of up to 10⁻² S/cm with effective ionic mobilities in the order of 10⁻⁸-10⁻⁷ cm²/(Vs) can be reached.

在这种作用下，在受控气氛下研究了基于聚噻吩的阴离子和阳离子聚合物的混合电导行为。共轭聚电解质是基于区域规则的聚噻吩主链，分别带有侧链磺酸根阴离子或咪唑鎓阳离子，分别与六氟磷酸四丁基铵和溴化物阴离子平衡。进行直流电，四点探针测量和阻抗谱分析以分离电子和离子电导率。光学吸收光谱用于陈述有关聚合物链的聚集并可视化电子掺杂行为。类似于纯共轭聚合物（例如聚（3-己基噻吩）），可以在10 ^-6以下的宽范围内调节电子电导率 通过强电子受体F ₄ TCNQ的外部掺杂通过顺序溶液掺杂实现S / cm至2.2 S / cm 。另一方面，显示出离子电导率强烈依赖于吸水程度。我们显示， 在有效离子迁移率达到10 ^-8 -10 ^-7  cm ² /（Vs）的情况下，可以达到高达10 ^-2 S / cm的值。
