Electropolymerization of pyrrole in 1-ethyl-3-methylimidazolium trifluoromethanesulfonate room temperature ionic liquid

Air and moisture stable ionic liquid like 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMICF 3SO 3) has been used as an electrolyte for the electrooxidative polymerization of pyrrole; the morphological structure of polypyrrole film formed on the anode was greatly affected, and the polymeri...

More Information
Summary:Air and moisture stable ionic liquid like 1-ethyl-3-methylimidazolium trifluoromethanesulfonate (EMICF 3SO 3) has been used as an electrolyte for the electrooxidative polymerization of pyrrole; the morphological structure of polypyrrole film formed on the anode was greatly affected, and the polymerization rate, electrochemical capacity and electroconductivity were significantly increased. Furthermore, it was also found that EMICF 3SO 3 could be recovered by a simple extraction of the remaining pyrrole monomer from the ionic liquid after use, and then reused without significant loss of reactivity for the polymerization.
