使用离子液体作为添加剂获得了高导电性的聚（3，4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）薄膜。当向导电聚合物中加入1-乙基-3-甲基咪唑四氰基硼酸盐（EMIM TCB）时，电导率增加到2084 S cm-1;这归因于PSS的相分离导致膜中的结构变化。与1-丁基-3-甲基咪唑四氟硼酸盐（BMIM BF 4）的比较研究表明，EMIM TCB具有更高的电导率和透光率，可以被视为以PEDOT：PSS/EMIM TCB为电极制备无铟锡氧化物（ITO）有机器件的最有前途的添加剂之一。
Highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films are obtained using ionic liquids as additives. Upon adding 1-ethyl-3-methylimidazolium tetracyanoborate (EMIM TCB) to the conducting polymer, the conductivity increases to 2084 S cm-1; this is attributed to the phase separation of PSS leading to a structural change in the film. A comparative study with 1-butyl-3-methyl imidazolium tetrafluoroborate (BMIM BF4) shows that EMIM TCB gives higher conductivity and transmittance and can be regarded as one of the most promising additives for the preparation of indium tin oxide (ITO)-free organic devices using PEDOT:PSS/EMIM TCB as electrodes.
