Curvature-morphing of glassy polymers by localized photothermal heating |
| 초록 |
Recently, shape-reconfigurable materials have received large attention for contactless shape-morphing by external stimuli. In particular, ink-patterned 2D pre-stretched polymer sheets are attractive for photothermal shape-morphing into 3D architectures. Upon exposure to near infrared light, localized photothermal heating at patterned areas results in programmable shrinkage of polymer sheets by operating as a hinge. To date, most studies focused on architecture of 3D geometry of glassy polymers via linear hinge patterns. Realization of complex 3D construction requires generation of curvature while linear patterns require complicated design and analysis to predict the 3D actuation. Herein, we report a simple strategy for curvature generation toward complicated 3D construction by introduction of radial patterns. We will discuss quantitative evaluation of pattern effectiveness and FEM simulation. |
