10x 3 mL of all concentrations of 2NapFF-Na (5-100 mg/mL) and 2NapFF-TBA (5-75 mg/mL) were formed as described in Section 1.3. 2 mL were then pipetted into 7 mL Sterilin vials and then placed into an oven set to 60 °C for 1 hour. After an hour, solutions were allowed to cool undisturbed on the bench at room temperature over two hours. After two hours, samples were examined using rheology.
