“…Besides, the phosphorous containing groups’ (P–O–P, P + –O − , P=O, P–O–C, P=OOH) vibrations were also observed at 1128 cm − 1 and 1187 cm − 1 , showing the incorporation of AC into PIN main chain. Furthermore, no extra peak was observed in composite samples except for characteristic peaks of polymer salt and AC [ 28 , 29 ]. The relative shift in peaks positions and presence of peaks for AC in composited samples confirms the formation of AC@PIN composite [ 29 , 30 ].…”

The present study is aimed at the synthesis and exploring the efficiency of a novel activated carbon incorporated polyindole (AC@PIN) composite for adsorptive removal of Malachite Green (MG) dye from aqueous solution. An AC@PIN hybrid material was prepared by in situ chemical oxidative polymerization. The physico-chemical characteristics of the AC@PIN composite were assessed using Fourier-transform infrared spectrometer, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectroscopy, ultraviolet visible spectroscopy, and determination of point of zero charge (pHPZC). A series of adsorption studies was conducted to evaluate the influence of operational parameters such as pH, contact time, initial dye concentration, AC@PIN dosage, and temperature on dye adsorption behavior of developed composite. A maximum dye removal percentage (97.3%) was achieved at the pH = 10, AC@PIN dosage = 6.0 mg, initial dye concentration 150 mg L−1, and temperature = 20 °C. The kinetic studies demonstrated that the adsorption of MG on AC@PIN followed pseudo-second-order model (R2 ≥ 0.99). Meanwhile, Langmuir isotherm model was founded to be the best isotherm model to describe the adsorption process. Finally, the recyclability test revealed that the composite exhibits good recycle efficiency and is stable after 5 cycles. The obtained results suggest that AC@PIN composite could be a potential candidate for the removal of MG from wastewater.

“…However, the capacitance of AC is only 40–70 F/g because of its large number of micropores, which are not easily accessed for electrolyte ions. Great efforts have been made to tune the properties of AC . For example, AC could be modified by sulfur functional groups, leading to 40% increase of capacitance at current density of 1.4 A/g .…”

Summary It is important to tune the surface and pore structures of carbon materials for their application in capacitors. Herein, a novel microwave‐based approach is demonstrated to significantly increase the capacity of a supercapacitor. After activated carbon (AC) with KOH was treated by microwave heating only for 8 min, its symmetrical double‐layer capacitor increased from 68.6 to 107.9 F/g at current density of 0.2 A/g with 2 M KOH aqueous solution. The excellent capacity retention of 96% was obtained even after 4000 galvanostatic charge/discharge cycles at current density of 5 A/g. This microwave approach is much more efficient than the conventional heating process to tune the electrochemical properties of AC. Copyright © 2016 John Wiley & Sons, Ltd.

Polyaniline (PANI) was successfully deposited by means of cyclic voltammetry technique from 0.10 M aniline containing 0.30 M oxalic acid and 1 g/l H3BO3 solution on AISI 4140 steel electrode. In this investigation nominate scan rates 25, 50, 75, and 100 mV/s have been examined. PANI film was characterized using optical microscope; it was covered with a dark green-yellow homopolymer film of strongly adherent homogeneous characteristic. The corrosion behaviour of the steel electrodes with and without PANI film in 3.5% NaCl solution was investigated through anodic polarization curves. The results indicated that PANI coating led to decrease of the permeability of metallic plating. The PANI homopolymer film provided an effective barrier property and a remarkable anodic protection to substrate.
