Wormlike micelles are considered a "living" system. Wormlike micelles are transient and have unique viscoelastic behaviour. Under shear, the micelles can continuously break and reform. Many other factors are known to influence micellar growth and properties such as pH, the addition of salt, and temperature. We investigate here the effects of shear specifically to gain the most reproducible data possible from these living systems. We selected exemplar solution concentrations of 10, 40 and 100 mg/mL 2NapFF-Na based on our SAXS data. These concentrations have different structures and packing, as discussed in the main text, and hence could be affected differently by the investigated factors.
