Rheological Characterization of Samples

The rheological properties of the samples were tested using a rotational rheometer (Model: MCR92, from Anton Paar, Austria) [15 (link), 49 (link)–51 (link)]. An appropriate amount of sample was taken and placed on the sample stage, the model of the test rotor was 50 mm for parallel plates, the gap was set at 1 mm, and the test temperature was 25 °C. Set the strain scanning, scanning range 0.01–1000%, logarithmic point, frequency set to 1 Hz. Set up angular frequency scanning, scanning range 0.1–100 Hz, logarithmic point taking, strain setting 1%. Set time modulus profile, linear scan at 0–10 min, gap 0.6 mm, strain 1%. Set the shear mode with a shear rate of 0.1–100 s⁻¹ for the rheological behavior and logarithmic point taking.
