To understand the implications of how this change in solution aggregation can influence flow-induced alignment, we carried out similar retardance imaging of the PII-2T in CB/DMF solution at 10 mg/mL in shear and extensional flow. Figure and B show the shear and extensional retardance images of the CB/DMF solutions (bottom) in comparison to the pure CB case (top) at the highest corresponding strain rates. The spatial profiles are surprisingly different, with the CB/DMF aggregates being more easily aligned due to having slower orientational relaxation. This is clearly shown in Figure where the retardance streak persists throughout the outlet channels for the CB/DMF solution while it decays quickly outside the stagnation point in the pure CB solution. On the other hand, the CB/DMF solution reaches a lower degree of alignment compared to the CB solution at higher strain rates. This can also be seen in Figure and B where the retardance at the walls for shear and at the stagnation point for extension is lower for CB/DMF compared to CB. Figure and D further demonstrates this as the retardance versus strain rate is compared between the two solutions for shear and extensional flow. In both shear and extension cases the retardance of the CB/DMF solution is higher at lower strain rates.
