“…The FTIR absorption spectra of the PANI powder and of PANI grafted on the modified glass fiber are qualitatively compared in Fig. 4 and are in good agreement with the previously reported results for PANI (30,31). The main peaks at 1590 and 1500 cm −1 can be assigned to the stretching vibrations of quinone and benzene rings, respectively.…”

“…1 . The peak at 580 cm -1 is attributed to vibration of the sulfate anions which ionized from the oxidizing agent (PPS) during the polymerization process; the ionized sulfate ions linked to nitrogen atoms in PANI by ionic bond which explains why PANI doped in part of it [31,32,[34][35][36][37]. After coating graphitic materials (MWCNTs and G) with PANI, the spectra reflect the presence of polymer overlay.…”

This study reported the doping of polyaniline (PANI) with graphene (G) and multi-walled carbon nanotubes (MWCNTs) by in situ polymerization. The molecular structure of PANI and its composites was observed by FTIR, which shows that the intensity of composites peaks are higher than pure PANI due to charge transfer between the PANI and graphitic allotropes. The structural information and crystallinity of PANI and its composites can be deduced from X-ray diffraction. The morphological characterization was observed by transmission electron microscope, which elucidated that aniline molecules were physically adsorbed and polymerized on the surface of graphene and MWCNTs due to p-p* electron interaction. PANI represents as an external layer of composites with several diameters depending on the PANI deposition degree, where the cores are G and MWCNTs. The conductivity measurement clarified the conductivity value of 0.1 wt% G in PANI matrix is higher 17 times than PANI without it.

“…The second significant change was observed for the absorption at ~1300 cm -1 which consists of the bands at ~1328 cm -1 and ~1285 cm -1 . As known, the absorption band at ~1285 cm -1 in EB is normally assigned to the C-N stretching vibration [29], whereas that at 1328 cm -1 to the radical-cation C-N .+ stretching vibration observed normally in the doped PANI chains [30][31][32]. A more pronounced band at 1328 cm -1 observed for the film prepared under alternating magnetic field testifies to a higher protonation level of the polymer chains in this case.…”

Effect of the applied magnetic field on formation of complex polyaniline films

Formation of complex polyaniline (PANI) films with diamagnetic TCNQ and paramagnetic metal ion impurities cast under applied magnetic field was studied. It has been found that the applied magnetic field affects interaction of PANI chains with the impurities and induces formation of magnetically ordered regions in the complex film doped by paramagnetic metal ions in contrast to the reference film of the same composition but prepared under ambient conditions. The magnetically ordered regions have been observed directly by scanning magnetic force microscopy. It was found a correlation in distribution of the magnetically ordered regions and peculiarities of the surface relief of a film. Electronic absorption spectra and conductivity measurements showed that an applied stationary magnetic field can suppress the interaction of PANI chains and paramagnetic metal ions and lowers conductivity of the resulting complex film up to one order of magnitude as compared with the reference film. An alternating magnetic field was found to improve interaction of PANI and diamagnetic TCNQ molecules. The mechanisms of the magnetic field influence on the complex film formation are discussed.
