MWCNTs with outer diameters of 110-170 nm (1.0 g) was reacted with potassium permanganate (10 g) (1:10 mass ratio MWCNT to potassium permanganate in a vigorously-stirred mixture of concentrated sulfuric acid (280 ml) and concentrated phosphoric acid (32 ml) (9:1 acid ratio) at 65 C for 4 h.
2. The reaction mixture was then cooled to room temperature and poured over ice water (800 ml) containing hydrogen peroxide (40 ml, 30 %).
3. The resulting mixture was congealed overnight then filtered (0.2 mm mesh PTFE from Millipore), and washed in succession with hydrochloric acid (30 %), ethanol (100 %), and diethyl ether (anhydrous).
4. The final black material was dried at low heat (65 C) in a vacuum oven overnight.
2.2. Synthesis of conducting polymers
1. The pyrrole (0.8mol, 1.67ml) was dissolved in 30 ml of water and ethanol mixture (1:1) and sonicate for30 min.
2. Then ferric chloride solution (0.8 mol ferric chloride in 20 Ml of water, 2.6g) was added dropwise to the pyrrole under vigorous stirring for 24 h.
3. The obtained material was washed several times with a mixture of water and ethanol until the solution became colorless, and dried in a vacuum at 75 oC for 24 h.
2.3. Synthesis of nanocomposites
1. First, graphite oxide was dispersed in 50 ML of water under ultrasonication for 30 min.
2. The pyrrole (0.08 mol) was dissolved in 30 ML of water and ethanol mixture (1:1).
3. The resultant solution was then added to the dispersion of GO solution under ultrasonication for another 30 min.
4. The ferric chloride solution (0.04 mol ferric chloride in 20 Ml of water) was added dropwise to the pyrrole and GO mixture under vigorous stirring for 24 h.
5. The weight ratio of pyrrole to graphite oxide was varied as 99.5:0.5,and the resulting composite were donated as 0.5PPyGO,
6. The PPy/GO composites obtained was washed several times with a mixture of water and ethanol until the solution became colorless, and dried in a vacuum at 75 oC for 24 h. For comparison, the neat PPy was also polymerized by similar method without the presence of GO suspension.
2.5. Characterizations:
The synthesized materials were characterized using variety of techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and BET Surface Area and Pore Size Distribution Measurement Techniques, and electrochemical measurements. More information of these techniques is given below
