Electrochemical deposition and characterization of polypyrrole in electrolyte based on pyrrolidinium hydrogenosulfate protic ionic liquid

In this work, we investigated the electrochemical deposition of polypyrrole (Ppy) in an electrolyte containing the pyrrolidinium hydrogenosulfate [Pyrr][HSO4] protic ionic liquid. Herein, the Ppy films were prepared by sequenced and by continuous galvanostatic deposition methods. Cyclic voltammetry (CV) and electrochemical quartz crystal microbalance techniques were further used to investigate, in each case, the polymer growth, as well as, the...
