Figure 6: Elastic behaviours of NSGs.
From: Nano-structured smart hydrogels with rapid response and high elasticity
(a–d) Optical images showing the process of a NSG hydrogel being stretched to ~12 times its initial length in a tensile machine. (e–j) Typical stress–strain curves of NSG hydrogels of various compositions at room temperature (25 °C, <LCST; e–g) and at body temperature (37 °C, >LCST; h–j), in which σ* is the tensile stress and ε is the tensile strain. (e–h) The hydrogels are each loaded to a certain stretch before rupture and then unloaded. (f,g,i,j), The hydrogels are pulled to rupture in each test.
