Conductivity study of some polymer electrolytes based on polyacrylonitrile

Abstract

The present paper deals with the room temperature conductivity study of some polymer electrolytes based on polyacrylonitrile, ammonium tetraflouroborate as dopant, and propylene carbonate (PC) and polyethylene glycols (PEG300 and PEG600) as plasticizers. The additions of plasticizers having different dielectric constant have been found to modify the conductivity of polymer electrolytes. The increase in room temperature conductivity with plasticizer addition has been found to depend upon (1) the amount of salt present and (2) amount of plasticizers added. The polymer electrolytes prepared were characterized by Xray diffraction, scanning electron micrographs, infrared, thermogravimetric, and AC impedance measurements. The highest room temperature conductivity observed in case of these polymer electrolytes was ∼10-13 s/cm.

Effect of High Ammonium Salt Concentration and Temperature on the Structure, Morphology, and Ionic Conductivity of Proton-Conductor Solid Polymer Electrolytes Based PVA

“…Many researchers have already studied proton-conducting SPEs by incorporating ammonium salts to different polar polymers such as polyvinyl pyrrolidone, polyethylene oxide, polyvinyl alcohol, polyvinyl chloride, and polyacrylonitrile [ 11 , 12 , 13 ]. From the literature study, polyvinyl alcohol (PVA) has attracted great attention due to its good film-forming, good mechanical strength, biocompatibility, biodegradability, and nontoxicity [ 14 , 15 ].…”
