“…The spectral features closely resembled with the data available in the literature (Blaha et al, 2011;Sun et al, 1997;Zhang et al, 2016). A maxima in the region of 340-390 nm assignable to the (p-p*) transition (B-band), followed by a band at 614 nm (Q-band) were observed for the sample obtained using H 2 O 2 and FeCl 2 Á2H 2 O.…”

“…Additionally, the bands at 1171 cm À1 indicated the vibration modes of ES form (d(C-H)), confirming our sample to be ES form of PANI (Blaha et al, 2011). Other bands at 409, 448 and 519 cm À1 could be assigned to wagging and deformation modes of (C-N-C) bond.…”

“…Formation of an ordered PANI has been achieved under controlled synthetic conditions following twostep processes by changing the temperature of the growth of PANI (Surwade et al, 2009;Swapna Rao et al, 2002;Tang et al, 2009). Majority of the reports have employed Fe 2þ /H 2 O 2 as the catalyst/oxidant to generate nanofibres of PANI (Blaha et al, 2011;Sun et al, 1997;Wang et al, 2007), the possibility of stacking PANI chains in a particular orientation resulting in an ordered arrangement has not yet been explored. In this paper, a single-step and one-pot synthesis of ordered semi-crystalline PANI-ES by the chemical catalytic polymerization using H 2 O 2 /FeCl 2 Á2H 2 O and H 2 O 2 /VO(SO 4 )ÁH 2 O are described.…”

Polyaniline was synthesized by the chemical oxidative polymerization procedure at room temperature employing hydrogen peroxide (H 2 O 2 ) as oxidant and ferrous chloride (FeCl 2 Á2H 2 O) and vanadyl sulphate (VOSO 4 ÁH 2 O) as co-catalysts, respectively. The obtained polymers were characterized by high resolution powder X-ray diffraction, Fourier transform infrared spectroscopy, Raman, UV-Visible, photoluminescence spectroscopy, thermogravimetric Field Emission Scanning Electron Microscopy (FESEM) and Transmission Electron Microscopy (TEM) techniques. Ordered arrangement indicative of semi-crystalline nature of polyaniline was evidenced from the presence of intense reflection at d ¼ 13.72 Å in the powder X-ray diffraction pattern followed by two lesser intense peaks at 4.61 and 3.47 Å . Fourier transform infrared spectroscopy and Raman spectroscopic results indicated the polyaniline to be emeraldine salt form. Fibrous morphology was observed in scanning electron microscope images. Nearly 93% of Methyl Orange dye was adsorbed in 30 min by the ordered polyaniline at room temperature. No significant difference in the crystallinity and/or ordering was noticed in the powder X-ray diffraction pattern after dye adsorption. The correlation between the ordered structure of polyaniline and its higher adsorption property derived in the current study has the potential to fabricate devices consisting polyaniline to detect dye molecules.

“…Catalytic processes giving water as a byproduct are thus more desirable. Polymerization of ANI has been accomplished with catalytic systems such as Cu 2+ /O 2 , Fe 3+ /O 3 , Fe 3+ /H 2 O 2 , Fe 2+ /solid complexes of H 2 O 2 or various peroxidase/H 2 O 2 systems …”
