Abstract
In this communication, we report a composite macroporous hydrogel sheet that can rapidly transform into multiple 3D shapes in response to near-infrared (NIR) light on demand. The transformation relies on the photo-thermal-induced asymmetric shrinking of the hydrogel material, which is further verified by finite element modeling.
摘要
在本通讯中，我们报道了一种复合大孔水凝胶片材，它能够根据需求在近红外（NIR）光照射下快速转变为多种三维形状。这种转变依赖于水凝胶材料的光热诱导不对称收缩，有限元建模进一步验证了这一点。
