Figure 9.

When samples were recovered via thermal triggering, followed by light triggering, successful triple-shape-memory behavior under cytocompatible conditions was demonstrated by the samples that contained GO, which showed statistically significant contractile length changes following both triggering events. In contrast, samples with no GO showed no significant change following the light triggering event. The strain recovered was calculated as the ratio of the sample length recovered to the original length. tBA-BA (tert-butyl acrylate-butyl acrylate), GO (methacrylated graphene oxide), and PCL (poly(ε-caprolactone)). * p < 0.05, ** p < 0.01, # p < 0.05 compared to the original length, ## p < 0.01, n = 3.
