The viscoelastic fluid was then transferred to an Anton Paar MCR-302 stress-controlled rheometer where all measurements were done on a 10 mm parallel plate geometry. The fluid was loaded and then sealed with mineral oil to prevent evaporation. All small-amplitude oscillatory shear experiments are performed with a shear stress of 5 Pa to stay within the linear viscoelastic regime of the material. Constant shear rate experiments are performed by with a logarithmic shear rate sweep from 0.1 rad/s to 100 rad/s.
