The Complex Micro-Nano-Structure of Polyaniline doped with Benzene Sulfonic Acid in the Presence of the Anionic Surfactant Sodium Dodecylbenzene (SDS)

Naar Nacira,

Résumé: The synthesis of polyaniline (PANI) doped with benzene sulfonic acid (BSA) was conducted in the presence of a micellar solution containing the anionic surfactant sodium dodecyl sulfate (SDS) as a soft template (PANI-BSA/SDS) via the chemical oxidation polymerization of the aniline. The formation of micelles depended on the reaction conditions and especially, the critical micelle temperature and the critical micelle concentration (CMC). By this synthesis way, it was expected that the coordination effect of both the micelles with inter-molecular interactions and the use of a sulfonated organic dopant (BSA) with low surface energy might result in molecular self-assembly giving ordered 3D- microstructures. The obtained samples were characterized by elemental analysis, Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), X-ray diffraction, scanning electron microscopy, (SEM), electron paramagnetic resonance (EPR) and electrical characterization. The XRD measurements of the PANI-BSA/SDS revealed the simultaneous presence of both persisting crystals of SDS and a typical semi-crystalline doped PANI. When minimizing the presence of crystalline SDS, the resulting material consisted of a poorly semi-crystalline doped PANI. Moreover, the electrical measurements showed that the PANI-BSA exhibited an electrical conductivity of 400 S/m and the PANI-BSA/SDS with a conductivity value of 1 S/m. polyaniline, benzene sulfonic acid (BSA), structural properties, soft template
