Self-organization of polymers at the solution/air interface driven by solvent evaporation produces a variety of complex patterns including coffee rings. Structure formation from evaporating droplets consisting of two nonvolatile solutes has been less explored regardless of its common existence and numerous technological implication. The synergy of phase separation of polymer blends, and their destabilization mediated by the interaction between solutes and substrates during controlled solvent evaporation, can lead to the formation of well-ordered complex nanostructures. In this study, we used evaporation-induced self-assembly process with continuous roll-casting system by a judicious movement that is unique in offering a nonlithographic route to creating highly ordered two-dimensional polymer patterns with a complex architectures. We observed the graphene pattern formations by utilization of the phase separation of two immiscible polymers on graphene substrate. |
