A noble, safe and electrochemically stable microporous IL-CNTs-PANI polymer electrolyte has been reported. In the microporous polymer electrolyte (MPE), polyvinylidene fluoride (PVDF) was doped with an ionic liquid (IL), carbon nanotubes (CNTs) and polyaniline (PANI). The surface structure and element composition of MPE film were measured by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and fourier-transform infrared spectroscopy (FTIR). The thermogravimetric analysis/differential scanning calorimetry (TGA/DSC) have carried out to characterize electrolytes’ thermal stability, and the electrochemical performance was measured by cyclic voltammetry (CV) and Tafel curves. It is found that a soft and porous MPE film can be obtained by changing the content of CNTs/PANI and the heat treatment temperature. Doping with different amounts of PANI has certain effects on the thermal stability and crystallization properties of MPE film. The prepared electrolyte membrane has good capacitance, wide electrochemical window (~3 V), certain charge transfer and ionic conductivity. Finally, the prepared electrolyte membrane was used to print a NO₂ gas sensor, which proved that the MPE has the potential to become a gas-sensing material for NO₂ sensors.

已经报道了一种高贵，安全和电化学稳定的微孔IL-CNTs-PANI聚合物电解质。在微孔聚合物电解质（MPE）中，聚偏二氟乙烯（PVDF）掺杂有离子液体（IL），碳纳米管（CNT）和聚苯胺（PANI）。通过扫描电子显微镜（SEM），X射线光电子能谱（XPS）和傅里叶变换红外光谱（FTIR）来测量MPE膜的表面结构和元素组成。进行了热重分析/差示扫描量热法（TGA / DSC）以表征电解质的热稳定性，并通过循环伏安法（CV）和Tafel曲线测量了电化学性能。发现通过改变CNT / PANI的含量和热处理温度可以获得柔软且多孔的MPE膜。掺杂不同数量的PANI对MPE膜的热稳定性和结晶性能有一定的影响。所制备的电解质膜具有良好的电容，宽的电化学窗口（〜3 V），一定的电荷转移和离子电导率。最后，将制备的电解质膜用于印刷NO₂气体传感器，证明MPE有潜力成为NO ₂传感器的气体传感材料。
