“…A broad peak at 3402.13 cm -1 is due to the N-H stretching vibration of the aromatic amine. The bands at 1068.92 and 674.19 cm -1 represent the symmetric stretching of the SO 3 group [18]. The bands are in agreement with the theoretical predictions and confirm the deposition of PANI over the surface of the CNT i.e.…”

“…Various dopant are used for doping of polyaniline which include p-toluene sulphonic acid (PTS), dodecyl benzenesulphonic acid (DBSA), camphor sulphonic acid (CSA), polyvinyl sulfonic acid (PVA) etc. [18]. However, HCl itself acts as a dopant for PANI but using a secondary dopant along with HCl enhance the electronic properties of the material and also the processability.…”

Composites of polyaniline and carbon nanotube (CNT) were prepared by in-situ chemical polymerization method using various aniline concentrations in the initial polymerization solution with p-toluene sulfonic acid (PTS) as secondary dopant and mechanical mixing of the PANI and CNT using different weight ratios of PANI and CNTs. The structural characterizations of the composites were done by Fourier transform infrared (FTIR) and Ultra violet visible spectroscopy (UV-Visible). Scanning electron microscopy (SEM) was used to characterize the surface morphology of the composites. It was found that the composites prepared by in-situ chemical polymerization had smoother surface morphology in comparison to the composites obtained by mechanical mixing. The capacitive studies reveal that the in-situ composite has synergistic effect and the specific capacitance of the composite calculated from cyclic voltammogram (CV) was 385.1 F/g. Thermal studies indicate that the composites are stable as compared to PANI alone showing that the CNT contributes towards thermal stability in the PANI-CNT composites

“…2a, the peaks at 1487 cm -1 and 1566 cm -1 respectively correspond to the C-C stretching vibration of the benzene ring and the quinoid ring. The peak at 1299 cm -1 is aromatic (C-N) stretching band of polyaniline, the broad and strong absorption peak at 1132 cm -1 corresponds to B-NH-B stretching vibration of polyaniline and the peak at 800 cm -1 is para-disubstituted benzene ring [36][37][38][39][40][41] . A peak appears at 1701 cm -1 in the curve of γ-Fe 2 O 3 @PANI-CHB (Fig.…”

Since MacDiarmid et al. 1 redeveloped polyaniline in 1984, polyaniline with its good thermal stability, chemical stability and electrochemical reversibility, excellent electromagnetic microwave absorption properties, low price of raw materials, simple synthetic method and unique doping-dedoping mechanism 2-6 , has become a research hotspot as the most promising conductive polymer materials 7-10. In recent years, conductive polyaniline and inorganic material composite 11-16 caused a great deal of interest, because the composite can improve performance of original material. Currently polyaniline composite material applied in many fields, such as all-plastic metal anticorrosion technology, electromagnetic shielding technology, antistatic technology, electrochromic, solar batteries, sensor elements, catalytic materials, stealth technology. Above all, polyaniline has good biological compatibility 17-20. The conductivity of polyaniline can last about 100 h in human body and currents through the conductor surfaces can control the shape and function of anchorage-dependent cells 21. So polyaniline can also be used as a carrier material in the magnetic targeting drug delivery system. The magnetic nanoparticles (such as γ-Fe 2 O 3 and Fe 3 O 4) has the advantage of chemical stability and biocompatibility and can be excreted out of the body regularly, while magnetic materials such as cobalt and nickel have certain physiological toxicity, the γ-Fe 2 O 3 and Fe 3 O 4 are usually applied to the biological field 22,23 .
