Fluid properties are known to be time-dependent due to entanglement rates. The rate of entanglement is slow and based on Brownian-motion. However, disentanglement is driven by strain/shear and is therefore quicker. Hence, when our samples are allowed to stand undisturbed on the bench, we remove the shear which would be responsible for continuously breaking the micelles. We therefore are allowing the wormlike micelles the chance to slowly grow and entangle, allowing the viscoelasticity of the solutions to increase. We see shear history impacts the rheological properties for 2NapFF concentrations of 10 and 40 mg/mL, where the viscosity gradually increases over the seven day period when left undisturbed. For 100 mg/mL, however, we see a gradual decrease in viscosity over the seven-day period when left undisturbed. We hypothesis that this is due to how viscous and concentrated these samples are. This concentration was visibly very viscous and moving onto the rheometer and lowering the geometry for measurement may have disturbed the samples. Lowering the geometry may have caused premature alignment before measuring, which would decrease the viscosity. The lowering of the geometry for measurement could have also applied shear to the sample which could have broken some wormlike micelles, again lowering the viscosity prematurely. In addition to the rate of stirring, the containers and stirrer bars used to prepare the samples also affects the sample viscosity, Figure . Stirring consistently at 1000 rpm for both sample containers, we see clear differences in viscosity trend over the seven-day monitoring period. For samples prepared in Falcon tubes and stirred with 25x8 mm stirrer bars, Figure , the viscosity comes to a steady state equilibrium after only one day of stirring at 1000 rpm. However, when stirring in a smaller container (Sterilin vial) and using a smaller stirrer bar (13x3 mm), we see a general decreasing trend in viscosity as stirring time is increased.
