“…1 shows the SEM microphotographs of the PANI and its composites. Granular morphologies are observed for the PANI and PANI-Au, while in the presence of PSS, the films of PANI-PSS and PANIAu-PSS appear compact and show better cohesion because the PSS used here not only served as the counterion but also served as a soft template in the formation of polyaniline [16,20,21], leading to good film-forming ability of the PSS-based samples [20]. To confirm the formation of Au, energy-dispersive X-ray (EDX) analysis was executed for the four samples (see the insets in Fig.…”

“…This approach is simple and versatile, and recently has been extended to prepare polyaniline-based binary nanocomposites such as polyaniline-poly(styrene sulfonic acid) [16] and polyaniline-poly(acrylic acid) [17]. Ternary polyaniline-poly(styrene sulfonic acid)-platinum nanocomposite was also successfully prepared through such a method [18].…”

Synthesis and Characterization of PSSA-Polyaniline Composite with an Enhanced Processability in Thin Films

This paper reports the synthesis and investigation of a polymer composite based on poly(4-styrenesulfonic acid) (PSSA) and polyaniline (PANI) directly obtained in an aqueous PSSA medium, with improved conductivity and solubility in polar solvents. The oxidative polymerization reaction of aniline takes place in-situ with PSSA as protonating agent. The synthesis was tested at three PSSA/PANI molar ratios, an intense green colored aqueous composite solution being obtained in each case. For comparison purposes, commercially available polyaniline and PSSA were also investigated. PSSA-PANI composites, PANI and PSSA were investigated through thermal analysis, Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy. Thin films of PSSA/PANI complex were spin coated on glass substrates which were further investigated through Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). Also, thin films of PSSA-PANI were deposited on interdigitated electrodes for dielectric measurements.

“…These nanofibers have application as biological sensors. Hopkins et al [26] prepared polyaniline/poly(sulfonated styrene) (PANI/PSS) nanofiber composites by an interfacial in situ polymerization technology. The high-molecular weight PSS encasing the PANI chains helps stabilize the charge carriers on the PANI by reducing the doping acid's mobility for applications in electromagnetic shielding and static charge dissipation.…”

Summary: Core‐sheath nanofibers with conductive polyaniline as the core and an insulating polymer as the sheath were prepared by electrospinning of blends of polyaniline with either polystyrene or polycarbonate. These unique core‐sheath structures offer potential in a number of applications including nanoelectronics. When polyaniline was blended with poly(methyl methacrylate) and poly(ethylene oxide), only isolated domains of polyaniline in beadlike structures were formed. The phase morphology of electrospun fibers is thought to be dependent on the high‐surface tension of the solution and the molecular weight of the polymers. Incompatibility of the polymers and low molecular weight of compositions played a key role in the formation of core‐sheath structures, as opposed to co‐continuous morphologies.TEM image of electrospun polyaniline/polystyrene nanofiber after staining by OsO4.
