Abstract

In this study, two different strategies for the synthesis of graphene are reported. In the first case, Oxidized Graphene Nanoribbons (GO) are obtained by the oxidative unzipping of Single-Wall Carbon Nanotubes (SWCNTs), as described in our previous work (1). Then, GO was dispersed in several different ILs and the resulting nano-dispersion were fully characterized, under a morphological and structural point of view (2). In particular, several studies performed by HR-TEM (High Resolution- Transmission Electron Microscopy), FT-IR (Fourier Transform-Infrared spectroscopy) and XPS (X-ray Photoelectron Spectroscopy), demonstrated that ILs were physically adsorbed on the GO surfaces, their edges and walls. The second approach concerns the electrochemical synthesis of graphene gels, covalently functionalized with ILs (3), by the etching of a graphite anode. Also in this case, HR-TEM, FT-IR and XPS analyses revealed interesting information on the interaction between ILs and GO. In particular, nitrogen XP spectra of functionalized GO presented a component ascribable to the coordination of N with electron-rich functionalities. This experimental evidence was observed in all the materials investigated, no matter the IL.
