As interactions between polymers and/or fibril aggregates emerge with increasing concentration, the effectiveness of flow to induce alignment diminishes. In solution processing of conjugated polymers where solvent evaporation occurs, the concentration rises drastically as the initial (semi-)dilute solution traverses a complex pathway towards a solid film. It is then important to consider exactly at what point during this process flow is used to maximize its effectiveness and potentially alter the multiscale assembly pathway. These findings give insight towards designing both the aggregation structure of conjugated polymers and the fluid flows inherent to solution processing to produce a synergy that can enhance alignment and the subsequent electronic performance of conjugated polymer thin films.
