Three different ionic liquids were prepared and examined as solvents for polyimide synthesis. The solubility of 4,4′-oxydianiline and pyromellitic dianhydride as starting materials in ionic liquids was first evaluated, and then their polycondensation was carried out. Although these starting materials were hardly soluble in 1-benzyl-3-methylimidazolium bis(trifluoromethane sulfonyl)imide (3), addition...
Polymer electrolytes based on the composite of nitrile rubber (NBR; poly(acrylonitrile-co-1,4-butadiene)) and Li(CF 3 SO 2 ) 2 N (Li(Tf) 2 N) were prepared and their ionic conductivity was evaluated. NBR with nitrile content of 33% was mixed with 25 wt% Li(Tf) 2 N to show the highest ionic conductivity, while still in the rubbery state. Furthermore, addition...
