a (GB1)8/DC-(FL)8 bilayer hydrogel strip achieved full-moon circular shape in PBS. The DC-(FL)8 layer was prepared in 7.0 M GdmCl solution. b The effects of GdmCl concentration on the bending angle of (GB1)8/DC-(FL)8 bilayer hydrogels. The DC-(FL)8 layer was prepared in 7.0 M GdmCl solution. c Reversible and repeatable bending of (GB1)8/DC-(FL)8 bilayer hydrogels with the environment switched between in PBS and in 7.0 M GdmCl for seven cycles (n = 4). Error bars are standard deviations.
