Reduced graphene oxide (rGO) is presently considered for many potential applications due to its unique properties. The stable conjugated structure of rGO is mostly associated with covalent functionalization strategy, which is more advantageous than non-covalent routes. In the present study, we prepared an efficient method for covalent functionalization of reduced graphene oxide (rGO) via Diels-Alder (DA) click reaction in deep eutectic solvents (DESs). Firstly, Poly(ionic liquid)s featuring furfuryl moieties (P(F-ILs)) was synthesized by the functionalization of poly(chloromethyl styrene-alt-maleic anhydride) with 1-methylimidazole and furfuryl amine. Then, the polymer was directly grafted on the surface of untreated rGO in choline:ethylene glycol (ChCl:EG) based DES without any catalyst. The obtained hybrid materials were characterized by FT-IR, TGA, FT-Raman spectroscopy, XPS and TEM. |
