Abstract

In this study, new proton conducting membranes were prepared using poly-2,2'-(m-phenylene)-5,5'-bibenzimidazole (PBI) and varying amounts of methylimidazoliumtriflate[MeIm/TfO], a protic ionic liquid, by the solution casting method. The thermal properties and conductivity of these membranes were investigated. The obtained parameters, such as high thermal stability (235–255°C) and the conductivity of 0.7–1.6 mS/cm at 145°C, indicate that PBI membranes doped with either MeIm/TfO or BuIm/TfO, which were previously studied by our group, are quite interesting for further investigation as potential electrolytes for PEMFCs.

掺杂甲基咪唑三氟丙烯酸原离子液体的新型 PBI 膜

摘要本研究采用溶液浇铸法，使用聚-2,2'-（间苯）-5,5'-联苯并咪唑（PBI）和不同量的原生离子液体甲基咪唑三氟甲烷[MeIm/TfO]制备了新型质子传导膜。研究了这些膜的热性能和电导率。所获得的参数，如高热稳定性（235-255°C）和在 145°C 时 0.7-1.6 mS/cm 的电导率，表明掺杂了 MeIm/TfO 或 BuIm/TfO 的 PBI 膜（我们的研究小组以前曾对其进行过研究）作为 PEMFCs 的潜在电解质，非常值得进一步研究。
