“…Owing to their unique properties there are varieties of applications of CNT which include supercapacitors and batteries, sensors, biological applications like bone tissue engineering and many more [5]. Recently, composites of the CNT and conducting polymers were a matter of immense research because the composite from these two important materials produce the synergistic effect and produce better applications than the individual materials [6][7][8][9]. CNT acts as good filler in the polymer composite compared to other carbon materials because of their high surface area.…”

“…Various conducting polymers have been investigated to be used in the composite preparation but out of these PANI acts as promising material because of its various properties like air stability, flexibility, light weight, high conductivity, ease of synthesis by chemical and electrochemical method and good processability [10,11]. Recently, PANI was investigated in the synthesis of PANI-CNT composites by using MWNT [7,9], SWNT [8] and carboxylated CNT [6,12].…”

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

“…To conquer this problem, many advanced materials are being investigated, such as conducting polymers, carbon nanotubes (CNTs), graphene and its derivatives, and metal oxides (Choi et al, 2011;Oztekin et al, 2011;Strong et al, 2012;Lei et al, 2014). However, these advanced materials have certain limitations, e.g., organic conducting polymers have low selectivity, sensitivity, and a lack of environmental stability (Zhang et al, 2011;Das and Prusty, 2012). One of the shortcomings of carbon nanotubes (CNTs) is the entrapment of molecules at interstitial sites, which decreases reproducibility (Musameh et al, 2011;Herrera-Herrera et al, 2012).…”

Electrochemical recognition of Hg (II) ions utilizing EDTA modified polyaniline (PANI)/Graphene Oxide (GO) composite is reported in the present communication. Graphene Oxide (GO) synthesis was carried out by a modified Hummer's method. Electrochemical characterizations, namely cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), were performed before and after modification of the composite. The topographies of the PANI/GO composite and EDTA_PANI/GO electrodes were studied using AFM. Roughness parameter values were compared for confirmation of surface modification. Fourier transform infrared spectroscopy (FTIR) was utilized for the compositional analysis of PANI/GO and EDTA_PANI/GO electrodes. The EDTA_PANI/GO composite exhibits sensitivity toward Hg (II) ions when probed using the differential pulse stripping voltammetry (DPSV) technique with a lower detection limit of 2 ppb. EDTA modified SS_PANI/GO composite (PANI/GO composite deposited on a stainless-steel substrate) showed superior sensitivity in the detection of Hg (II) ions. The sensitivity was observed to extend to 1 ppb, which is smaller than the maximum contaminant level (MCL) endorsed by the Environment Protection Agency (EPA, United States).

“…As magnetic nanoparticles, magnetite (Fe 3 O 4 ) nanoparticles are mostly investigated among the many magnetic materials owing to their interesting magnetic properties and are easy to synthesize, and have a wide range of potential applications in various fields, such as magnetic recording media, photonic crystals, microwave-absorbing materials, and biomedical applications (Wei et al 2012a , b ; Umare et al 2010 ; Zhang et al 2011 ; Kim et al 2008 ). Recently, various Fe 3 O 4 –PANI micro/nanostructures have been the focus of research because their properties are different from those of the corresponding bulk forms.…”

Highly regulated Fe3O4–polyelectrolyte-modified polyaniline (Fe3O4–PE@PANI) hollow sphere nanocomposites were successfully synthesized using an electrostatic self-assembly approach. The morphology and structure of the Fe3O4–PE@PANI nanocomposites were characterized using field-emission scanning electron microscopy, transmission electron microscopy, Fourier-transform infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, and X-ray photoelectron spectroscopy. The results showed that the as-prepared nanocomposites had well-defined sizes and shapes, and the average size is about 500 nm. The assembly process was investigated. Magnetization measurements showed that the saturation magnetization of the nanocomposites was 38.6 emu g−1. It was also found that the Fe3O4–PE@PANI nanocomposites exhibited excellent reflection loss abilities and wide response bandwidths compared with those of PANI hollow spheres in the range 0.5–15 GHz. The Fe3O4–PE@PANI nanocomposites are, therefore, promising for microwave absorption applications.
