Considering that the aggregates in CB/DMF are significantly easier to align, the higher alignment of fibril aggregates formed in pure CB at higher strain rates may be due to the internal structure of the aggregates. In other words, despite the CB/DMF aggregates being easier to align at weaker flows, at stronger flows the overall orientational order is ultimately limited by the alignment within the aggregate's internal structure. This then suggests that the internal structure of fibril aggregates in CB is more susceptible to reconformation by flow compared to that in CB/DMF. This process of aligning and/or ordering the aggregate's internal polymer structure can be described by another characteristic relaxation timescale, which should be much shorter than the orientational relaxation time of the overall aggregate and thus corresponding to higher strain rates. Considering that the fibril aggregates in CB are more flexible and are initially more disordered than fibril aggregates in CB/DMF, it is reasonable to assume that the relaxation time of the internal polymers within the fibrils in CB is slower than that in CB/DMF. Thus the internal structure of the CB fibrils would be easier to modify and align, resulting in a higher retardance at higher strain rates. These results highlight the importance of how the exact nature of solution aggregation not only influences the structure and ordering of aggregates but how the size, shape, rigidity, and internal structure of the aggregates can drastically alter its response to flow.
