The rheological properties of CTS gel were analyzed in a rotational HaakeRheo Stress 1 rheometer (Thermo Fisher Scientific, Karlsruhe, Germany) with cone-plate geometry (Haake C60/2° Ti, 60 mm diameter, 0.105 mm cone-plate gap). The shear profile was evaluated following a ramp-up stage (0–100 s−1 for 3 min), a constant shear rate stage (100 s−1 for 1 min), and a ramp-down stage (100–0 s−1 for 3 min). All measurements were taken in triplicate at room temperature and the steady-state viscosity was recorded at 100 s−1 (constant shear stretch).
Experimental results were then fitted to different mathematical models by regression analysis [4 (link)].
