Fig. 4: Tensile properties of hydrogels.
From: Stretchable slide-ring supramolecular hydrogel for flexible electronic devices
a Visual photos used to show the excellent ductility (ACA-PEG20000-ACA: Hy-α-CD = 1:5) and Optical photographs of the stretching of the hydrogel. b Tensile stress−strain curves of hydrogels with different polypseudorotaxane components. (black, ACA-PEG20000-ACA: Hy-α-CD = 1:0; red, ACA-PEG20000-ACA: Hy-α-CD = 1:5; blue, ACA-PEG20000-ACA: Hy-α-CD = 1:10). c Tensile loading−unloading curves of hydrogels with different polypseudorotaxane components at strain of 1600% (samples represented by different colors are the same as in Fig. 3c). d Fracture energy of Hy-α-CD/ACA-PEG20000-ACA hydrogel with the ACA-PEG20000-ACA: Hy-α-CD ratio of 1:0, 1:5 and 1:10.
