Pulsed Electrosynthesis of Polypyrrole in N-Butyl-N-Methyl-Pyrrolidinium Bis(Trifluoromethanesulfonyl)Imide Ionic Liquid for Electrochemical Sensors

摘要

Electrochemically polymerized materials based on heterocyclic aromatic monomers such as pyrrole, thiophene, aniline and their derivatives have received great attention mainly because their possible use in rechargeable devices and also as matrices for modified electrode surfaces (1). Conducting polymers modified electrodes have a simple procedure for synthesis and have advantages in the detection of analytes. In particular, they give good results when they are used for the immobilization of enzymes especially by covalent bonding on the functionalized polymer network (2-6). Compared with polyaniline and polythiophene modified electrodes, polypyrrole modified electrodes have attracted more attention in the field of biosensors, because of their biological compatibility, high conductivity and environmental stability (7).
