A coarse‐grained lattice‐gas model is developed to study the drying‐mediated self‐assembly of binary mixtures of nanoparticles (NPs). Three model systems are considered, corresponding to equilibrium phase separation between two NPs (A and B), to an amorphous state, and to an ordered, checkerboard‐like superstructure (see Figure; red: NPA; green: NPB; blue: solvent). The mechanism for self‐ordering depends on the nature of the equilibrium superstructure and on the dynamic coupling to the evaporating solvent.
