Figure 3

The shape-morphing behaviors of CS hydrogel films via changing the length-to-width () ratios. (a, b) Schematic illustration of the shape-morphing behaviors (bending moments of at the -axis direction, and at the -axis direction) of CS hydrogel films (certain thickness) via changing the length-to-width ratios. and are the length and width of the swollen CS hydrogel films, respectively. (c) The relationship between the and shows different shape-morphing behaviors of CS hydrogel films (as shown in the inserted images) with different (36 mm, 24 mm, and 12 mm) in the same range of ratios. (d) The relationship between the and shows different shape-morphing behaviors of CS hydrogel films (as shown in the inserted images) with different (1 mm, 2 mm, 3 mm, 4 mm, and 5 mm) in the same range of ratios. The scale bars are 5 mm.
