| Popis: | Hydrophilic RF-(MES)n-RF/and RF-(AMPS)n-RF/polyaniline (PAn) nanocomposites were prepared by the polymerization of aniline monomer in the presence of the corresponding oligomers. These fluorinated PAn nanocomposites were able to cause the gelation toward a variety of hydrophilic ionic liquids, although the parent RF-(MES)n-RF and RF-(AMPS)n-RF oligomers were not effective for the gelation of such ionic liquids. Oleophilic RF-(DOBAA)n-RF oligomer has no gelling ability toward the ionic liquids; however, this oligomer was able to disperse well the original PAn powders into methanol to afford the corresponding oligomer/PAn composites. Interestingly, the isolated composite powders after the removal of the solvent were found to cause the gelation toward some oleophilic ionic liquids. In these composites, RF-(MES)n-RF/PAn nanocomposite/ionic liquid gel (ionogel) was found to provide a higher ionic conductivity than that of the parent ionic liquid under the similar conditions.
