| Abstract: | The direct electropolymerization of pyrrole in [BMIM]PF6 microemulsion was investigated for the first time. The H2O/TX-100/[BMIM]PF6 (W/IL), bicontinuous (BC), [BMIM]PF6/TX-100/H2O (IL/W) subregions can be used as electrolytes for pyrrole electropolymerization. The use of IL microemulsion remarkably reduces the amount of IL. Furthermore, electrochemical measurements indicated that W/IL microemulsion was the optimal medium and its polymerization rate was the fastest. Compared with molecular solvent system (0.25 mol L−1 [BMIM]PF6/acetonitrile) and neat [BMIM]PF6, the resultant films electrodeposited in W/IL microemulsion possessed excellent electrochemical activity and uniform morphology. All the results indicated that the H2O/TX-100/[BMIM]PF6 microemulsion as electrolyte medium is the most suitable for electropolymerization of pyrrole. © 2012 Wiley Periodicals, Inc.
