Comparison of graphene impregnated with/without nanosilver prepared by submerged arc discharge method

In this study, submerged arc discharge method (SADM) was used to prepare graphene-nanosilver composites (graphene impregnated with nanosilver) and verified whether it can be prepared under different methods. The optical properties, zeta potentials, and particle sizes of the composites were analyzed through ultraviolet-visible spectroscopy and Zetasizer. The suspensibility of composites were much better than that of noncomposites. Then, we compared the components of composites and noncomposites through transmission electron microscopy. The results confirmed that even when fabricated from similar materials, the composites and noncomposites yielded by SADM featured significantly different properties.
