The folding of graphene nanostructures driven by ionic liquids is studied in this work using molecular dynamics simulations. Nanodroplets of selected ionic liquids, were placed on top of graphene nanoribbons, and the folding process was analyzed considering nanodroplets composition (types of anion and cation) and size, together with nanoribbons width and length. The dynamics of the folding process is analyzed and the effects of folded structures on the confined ionic liquids. The folding of complex structures like graphene flakes or flower-like flakes was also analyzed. Ionic liquid induced folding is discussed in comparison with graphene folding induced by water and organic solvents nanodroplets. Reported results show that ionic liquids nanodroplets are a suitable alternative for the nanoscopic engineering of graphene structrures.
