英文摘要	An effective approach to develop a novel macroscopic anisotropic bilayer hydrogel actuator with on-off switchable fluorescent color-changing function is reported. Through combining a collapsed thermoresponsive graphene oxide-poly(N-isopropylacrylamide) (GO-PNIPAM) hydrogel layer with a pH-responsive perylene bisimide-functionalized hyperbranched polyethylenimine (PBI-HPEI) hydrogel layer via macroscopic supramolecular assembly, a bilayer hydrogel is obtained that can be tailored and reswells to form a 3D hydrogel actuator. The actuator can undergo complex shape deformation caused by the PNIPAM outside layer, then the PBI-HPEI hydrogel inside layer can be unfolded to trigger the on-off switch of the pH-responsive fluorescence under the green light irradiation. This work will inspire the design and fabrication of novel biomimetic smart materials with synergistic functions.
