Deposition of graphene oxide/silver nanocomposite using non-thermal plasma jet

In this paper, a direct deposition method was used to print graphene oxide/silver (GO/Ag) nanocomposites from silver nitrate and graphene oxide suspension with reduction using a non-thermal plasma jet. Aerosol droplets of the solution were reduced to GO/Ag nanocomposite in the plasma and deposited on the substrate. The hybrid materials were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy and Raman spectroscopy. The XRD results showed that the face centered cubic phase of Ag nanoparticles were developed in crystalline planes. The FESEM images confirmed that graphene oxide surfaces were decorated by Ag nanoparticles. The EDS analysis demonstrated that Ag was introduced on GO surface successfully via the plasma jet. GO exhibited distinctive Raman scattering for its D and G band, which were at 1355cm-1 and 1590cm-1, respectively, but they were weak for sensitive quantification purpose. By deposition silver nanoparticles on the surface of graphene oxide Both D and G bands of GO get enhanced.
