Self-folding microscale origami patterns are demonstrated in polymer films with control over mountain/valley assignments and fold angles using trilayers of photo-crosslinkable copolymers with a temperature-sensitive hydrogel as the middle layer. The characteristic size scale of the folds W = 30 μm and figure of merit A/ W (2) ≈ 5000, demonstrated here represent substantial advances in the fabrication of self-folding origami.
自折叠微尺度折纸图案在聚合物薄膜中得以展示，通过使用具有温敏水凝胶中间层的三层光交联共聚物，可以控制山峰/山谷的分配和折叠角度。这里展示的折叠特征尺寸 W = 30 μm 和优值 A/W(2) ≈ 5000 代表了自折叠折纸制造的重大进展。
