“…These results are in agreement with the spectra reported by Chen, Stejskal, and Kertesz, previously [20,23,24]. The FT-IR spectra of the PANI-EB (Figure 1a) show an absorption peak in the region of 3379 cm À1 , due to the hydrogen bond of NH groups.…”

“…The post-processing technique, emulsion polymerization, and preparation of composites or blends are the other methodologies that have been developed to improve the solubility of PANI [16][17][18][19]. One other useful and common method to synthesis the modified polyaniline is the incorporation of flexible alkyl chains into the monomer or polymer backbone [20]. By introducing various alkyl halides into the emeraldine or leucoemeraldine base (LEB) forms of polyaniline, Zhao and co-workers [21] synthesized the N-alkylated polyaniline through the N-alkylation method.…”

This study aims to explore an effective route for the preparation of conductive N-substituted polyaniline by incorporation of hexadecyl side chains into the fully reduced form of nano-structured polyaniline leucoemeraldine base. For this purpose, at first nano-structured emeraldine salt polyaniline was synthesized by interfacial chemical oxidative polymerization. The dark green product salt was neutralized by an ammonia solution in order to give us an emeraldine base (EB). Thereafter, the reduced form of nano-structured polyaniline was prepared by treating the obtained EB with phenylhydrazine in methanol. The excess amount of butyllithium was applied to abstract protons from the amine nitrogens of nanostructured LEB polyaniline chains. Thereafter, deprotonated polyaniline was reacted with hexadecylbromide to prepare poly(N-hexadecylaniline) through N-grafting reaction. The obtained poly(N-hexadecylaniline) was characterized using Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry, and thermal gravimetry analysis (TGA). The average diameters of unsubstituted and substituted polyaniline particles were determined by particle size analyzer. The optical properties of the poly(N-hexadecylaniline) in the undoped and doped state were obtained using UV-vis spectroscopy and the electrical conductivity of the sample was measured using sample in which the conductive materials were sandwiched between two Ni electrodes at room temperature. Also, electroactivity of the synthesized polymer was investigated under cyclic voltammetric conditions on the surface of the working glassy carbon electrode. The solubility of the obtained polymer was examined in common organic solvents.

“…The vibrational bands observed for the polyaniline salt are reasonably explained on the basis of the normal modes of aniline and benzene [21], a broad band at 3440 cm À1 assigned to the N-H stretching vibration. The presence of bands at 2920 and 2850 cm À1 are assigned to asymmetric and symmetric aliphatic C-H stretching vibrations, respectively [22], indicates the existence of the alkyl substituents in the polyaniline chain. This peak proves the presence of dodecylhydrogensulfate dopant in the polyaniline system.…”
