a Conductivity of BBL:PEIlin and BBL:PEIbra for different PEI content. b Evolution of conductivity of BBL:PEIlin in air for 24 h and thermal stability when subjected to annealing at 200 °C in nitrogen atmosphere over 24 h. c Stability of BBL:PEIlin exposed to common organic solvents (chloroform (CF), chlorobenzene (CB), 1,8-diiodooctane (DIO), dimethylformamide (DMF), and dimethylsulfoxide (DMSO)), showing changes in conductivity. Error bars indicate the SD of ten experimental replicates.
