Temperature dependent dynamic light scattering measurement was performed for S12 sample at 1 g/L concentration with Zetasizer Nano-ZS (Malvern instruments, Malvern, UK). The sample prepared for the turbidity measurement was taken into a clean disposable cuvette and the intensity averaged hydrodynamic diameters of the aggregates were collected over three consecutive runs at 173° scattering, within the temperature interval of 10 °C to 50 °C with 5 °C steps after an equilibrium time of 60 seconds.
