a Photos of PAA240k-AM after swelling for 48 h and PAA3k-AM after 6 h. Red lines circle out the hydrogel throughout swelling. b Swelling evolution of PAA240k-AM and PAA3k-AM across time. c SAXS profiles of PAA240k-AM before and after swelling with Lorentzian peak approximation. d Photos of swelled PAA240k-AM throughout the cycling at λ = 2. e Successive loading curves of swelled PAA240k-AM at λ = 2, λ = 3, and λ = 4. The stretch rate is 3 cm−1. f cyclic loading curves of swelled PAA240k-AM at λ = 2 for 100 cycles.
