The 3D shape-morphing degree of hydrogels depends on the pattern width (width: spacing = 1:1), pre-cross-linking time, and hydrogel thickness. Specifically, increasing the pattern width from 200 μ m to 3200 μ m decreases the bending degree of the resulting rolling structure from 2430°±28.6° to 1080°±27.5° correspondingly. jepang 4d
