| Résumé : |
Ionic liquids like 1-butyl-3-methylimidazolium chloride ([BMIM] Cl, 1-butyl-3-methyl-imidazolium hexafluorophosphate [BMIM] PF6, 1-butyl-3-methyl-imidazolium tetrafluorobrate [BMIM] BF4, 1-butyl-3-methyl-imidazolium bis (trifluoromethylsulfonyl) imide [BMIM] NTf2) were used as doping elements in polyaniline. Pure polyaniline (EB) and polyaniline doped with different anions of ionic liquids (ESs) were chemically synthesized using ammonium peroxydisulphate (APS) and ionic liquids as oxidants. Junctions have been prepared by evaporating chalcogenide materials (ZnSe, CdSe) on conducting polyaniline (EB & ESs) pellets using a vacuum evaporation technique. I-V characteristics of junctions have been studied at room temperature using the Keithley electrometer 6517A. I-V measurements show the rectification effect. A junction of ES [BF???] anion may be preferred over the other junctions due to its low ideality factor and maximum rectification ratio. |
