The Energy Storage Performance of the Graphene Oxide/Polyaniline Composite

Abstract

Graphene oxide (GO)/polyaniline (PANI) composite are synthesized via in situ polymerization in the presence of grapheme oxide under acid conditions. The GO/PANI was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM) and electrochemical testing. The cathodes prepared using PANI and GO/PANI delivered initial discharge capacities of 78mAh/g and 104.4mAh/g ,respectively stable reversible capacities of 58.5mAh/g and 103.7mAh/g after 50 chargedischarge cycles. The GO enhances the discharge capacity of the PANI electrode material. GO/PANI is a good candidate as electrode material in lithium ion batteries

Preparation and characterisation of silver nanoparticles/graphene oxide hybrid nanofiller reinforced-polyaniline

“…For GO@PANI, the peak around 1566 and 1483 cm –1 is due to C = C stretching vibration of quinoid (Q) and benzenoid (B) rings, suggesting that the GO can be successfully deposited on the surface of the PANI matrix. A band appeared at 1142 cm –1 is attributed to the N–Q–N stretching of the quinoid ring, which indicated that the PANI molecular chains have been embedded on the surface of the GO [34, 35].…”

“…The Ag@PANI nanocomposite shows the presence of the fcc crystal plane of AgNP and also the emeraldine salt form of PANI matrix. The GO@PANI nanocomposite shows diffraction peaks at 2 θ value of 20.43° and 25.91° corresponding to (020) and (200) diffraction plane of PANI matrix, respectively [35]. However, the diffraction peak of GO does not appear because GO is fully contacted and uniformly dispersed within the PANI matrix [37].…”
