Polymerizations were conducted using the ionic liquid monomer 1-vinyl-3-ethylimidazolium bis(trifluoromethanesulfonyl)amide ([Veim][TFSA]) as well as mixtures of this monomer with ethyl methacrylate (EMA). [Veim][TFSA] plays an important role in that it provides stabilization of rGO monomer dispersions, presumably via π–π interactions between rGO and [Veim][TFSA]. If the EMA:[Veim][TFSA] ratio is too high, rGO precipitates during preparation of the monomer phase of the miniemulsion. Interestingly, it was demonstrated that addition of a small amount of the homopolymer of [Veim][TFSA] leads to significantly improved rGO stability (more so than the effect of [Veim][TFSA] monomer), thus enabling preparation of polymer nanoparticles containing higher amounts of EMA.
