(a) The tensile stress–strain curves of poly(AAm-co-MA/Rh) hydrogel (black line), poly(AAm-co-MA_0.75-co-C12_0.25/Rh) hydrogel (red line), poly(AAm-co-MA_0.5-co-C12_0.5/Rh) hydrogel (blue line), and poly(AM-co-MA-co-C18/Rh) hydrogel (purple line), with a solid content of 70 wt% and the same Rh crosslinker concentration of 0.5 mol% of MA. Emission spectra of (b) poly(AAm-co-MA_0.5-co-C12_0.5/Rh), (c) poly(AAm-co-MA_0.75-co-C12_0.25/Rh), and (d) poly(AAm-co-MA-co-C18/Rh) hydrogels with a solid content of 70 wt% recorded at increasing strain levels during uniaxial stretching. The increment of fluorescence-intensity ratio I₆₀₀/I₄₄₀ as a function of (e) stretch ratio and (f) stress level for the poly(AAm-co-MA/Rh) hydrogel (black line), poly(AAm-co-MA_0.75-co-C12_0.25/Rh) hydrogel (red line), poly(AAm-co-MA_0.5-co-C12_0.5/Rh) hydrogel (blue line), and poly(AM-co-MA-co-C18/Rh) hydrogel (purple line).
