Structuring of RTILs at flat surfaces and inside slit pores. (a) Number density profile of the center of mass of [C_nMIM][BF₄] ionic liquids (full atomistic models) confined between two neutral graphene planes. Reproduced with permission from ref (319). Copyright 2019 American Chemical Society. (b–d) Density profiles of [C_nMIM][BF₄] ionic liquids (coarse grained models) confined between negatively charged surfaces (−32 μC cm^––2). The snapshots illustrate the segregation of the aliphatic chain toward the interior of the films. The anions ([BF₄]^–) are represented as blue spheres, and the cations are colored according to the color scheme in (e). (b–e) Reproduced with permission from ref (233).
