Figure 1
Rheological characterization of hydrogel mixtures with S1, S2, S3, S4 and S5 (3.0, 3.25, 3.5, 3.75 and 4.0% (w/v) SA and 4% (w/v) GL respectively). (A) Storage modulus G′ and loss modulus G″ under different angular frequencies. With the increase in SA concentration storage and loss modulus was increased. (B) Tan δ vs frequency of the hydrogel mixtures. Tan δ values were found <1 for all the hydrogel mixtures. (C) Storage modulus G′ and loss modulus G″ at different concentrations of SA from oscillation time sweep. Storage modus was increased with the increase in SA concentration. (D) Histogram shows the increase in storage modulus with increasing SA and GL concentrations in the hydrogel. (E) Viscosity of hydrogels at different shear rate. Viscosity of all the hydrogel mixtures decreased with increasing shear rate.
