a Top-view and side view of woodpile PW@NC at room temperature (RT) and 80 °C, respectively. Before and after treatment, the constant size and morphology indicate 3D-printed PW@NC stability even under 100 g loading. b, c 3D-pattern determined shape-change of PW@NC at room temperature (b) and shape-change above phase-change temperature (60 °C) (c). d–g 3D shape-change of CNT/PW@NC from in-plane to 3D spiral shape upon pulling (d, e) and complete reversion after re-heating (g). f CNT/PW@NC fixes the 3D shape at RT. The line spacing of the in-plane spiral is 2.0 mm. h Light-to-thermal conversion curves (h) and images (inset) of PW, 3D-printed PW@NCs, CNT/PW@NCs, and woodpile CNT/PW@NCs. The illumination was conducted under simulated sunlight (100 mW cm−2) for 1000 s.
