A) Average swelling ratio of the hydrogel formulations investigated for potential use in the composite device. The results demonstrate a higher swelling capacity in the hydrogels utilizing 10 kDa PEG, and the highest degree of swelling with a decreased weight percentage of NVP. B) Average shape recovery percentage of the three SMP foam formulation investigated within this research when submerged in 37°C RO water, which demonstrates the most rapid shape recovery in H40 foams. The number appearing after “H” in the SMP foam nomenclature refers to the ratio of HPED to TEA equivalents within the foam composition, where the crosslink density increases as the number increases. Data shown as mean ± standard deviation (n = 3 for swelling data and n = 5 for shape recovery data). * denotes statistical significance (p = 0.05) according to one-tailed Student’s t-test.
