Samples were stirred at three different rates, keeping the container and stirrer bar size constant. Stirring method 1 stirs the samples continuously at 400 rpm (set by stirrer plate) for seven days. Method 2 stirs the samples continuously at 1000 rpm (set by stirrer plate) for seven days. Method 3 stirs the samples overnight at 400 rpm (set by stirrer plate) to create a homogeneous sample and are then left undisturbed to stand for the remaining six days. Data collected are shown in Figure . Using stirring method 1 (400 rpm) we see in general a gradual decrease in viscosity over the seven-day period. Using stirring method 2 (1000 rpm), we see solutions of concentration 10 and 40 mg/mL 2NapFF come to equilibrium viscosity after one day stirring at this higher shear rate. Comparing the 40 mg/mL solutions stirred at 400 rpm and 1000 rpm, the equilibrium viscosity is established quicker at the higher shear rate. At 1000 rpm stirring, equilibrium is reached after one day, however when stirred at the slower rate of 400 rpm, the equilibrium viscosity is not reached until day five.
