“…The nanosheets are observed to be flat, light, and transparent and they appear to be larger than 1.5 µm and to be situated on top of the copper grid which is used during HRTEM analysis [ 42 ]. The wrinkles and the bends that are observed are due to the abundant defects and functional groups during the oxidation process which takes place over a period of 5 days [ 43 , 44 ]. These nanosheets also appear to be extremely dispersed in water due to the existence of topological features along the overlapping of the nanosheets [ 45 , 46 , 47 ].…”

Graphene oxide (GO) decorated with silver (Ag), copper (Cu) or platinum (Pt) nanoparticles that are anchored on dodecylbenzene sulfonic acid (DBSA)-doped polyaniline (PANI) were prepared by a simple one-step method and applied as novel materials for high performance supercapacitors. High-resolution transmission electron microscopy (HRTEM) and high-resolution scanning electron microscopy (HRSEM) analyses revealed that a metal-decorated polymer matrix is embedded within the GO sheet. This caused the M/DBSA–PANI (M = Ag, Cu or Pt) particles to adsorb on the surface of the GO sheets, appearing as aggregated dark regions in the HRSEM images. The Fourier transform infrared (FTIR) spectroscopy studies revealed that GO was successfully produced and decorated with Ag, Cu or Pt nanoparticles anchored on DBSA–PANI. This was confirmed by the appearance of the GO signature epoxy C–O vibration band at 1040 cm−1 (which decreased upon the introduction of metal nanoparticle) and the PANI characteristic N–H stretching vibration band at 3144 cm−1 present only in the GO/M/DBSA–PANI systems. The composites were tested for their suitability as supercapacitor materials; and specific capacitance values of 206.4, 192.8 and 227.2 F·g−1 were determined for GO/Ag/DBSA–PANI, GO/Cu/DBSA–PANI and GO/Pt/DBSA–PANI, respectively. The GO/Pt/DBSA–PANI electrode exhibited the best specific capacitance value of the three electrodes and also had twice the specific capacitance value reported for Graphene/MnO2//ACN (113.5 F·g−1). This makes GO/Pt/DBSA–PANI a very promising organic supercapacitor material.

“…The spectra show characteristic peaks of PPy. 19,20 The peaks at 610, 675 and 789 cm À1 originated from the C-H wagging vibrations. The peak near the 909 cm À1 can be attributed to the C-H out-of-plane deformation vibrations.…”
