The solutions were loaded on the Peltier plate(pre-heated to 80 ◦C) and its periphery was coated with paraffin oil to avoid water evaporation. After a conditioning step of 5 min, the samples were
cooled down to 55 ◦C (temperature at which the film-forming solutions were spread onto the glass plates) at a rate of 1 ◦C/min, while a small amplitude oscillatory shear strain was applied at 6.28 rad/s (1 Hz)
