Electrochemical polymerization of aniline in a protic ionic liquid with high proton activity

Electrochemical polymerization of aniline in conventional protic ionic liquids (PILs) usually requires an exogenous proton source or the aniline monomer pre-protonation to obtain high quality polyaniline (PANI). In the present work, a proton functionalized ionic liquid pyrrolidinium hydrogenosulfate ([Pyrr][HSO4]), which has high proton activity, has been tried for the first time as an electrolyte for the aniline electropolymerization. It is...
