Mechanical properties of BSAMA cryogels (B5, B10, and B15). (A) Shape recovery experiments. 5% w/v BSAMA cryogels (B5) returned to the original shape when the stress was removed. (B) Strain–stress curves were recorded during the axial loading. (C) Maximum stress at a break point. (D) Maximum strain at a break point. (E) Young’s modulus was determined by the slope of the stress–strain curve from 10% to 20% strain. n = 3, *: p < 0.05; **: p < 0.01, ***: p < 0.005, ****: p < 0.001, NS means no significant difference between the samples at the extremities of the line.
