Abstract
the photothermal effect. Moreover, due to the structural gradient resulting from the spontaneous deposition of RGO during the deswelling process, CLCEs show a stacked structure of the helical CLC layer and RGO-dispersed amorphous layer, which are capable of undergoing multiple reversible 3D deformations. The reversible deformations of biomimetic devices such as petal-like films imitating blooming flowers, thin strips imitating plant tendrils, and a cobweb-inspired catching net are achieved to demonstrate applications of this single-layer RGO/CLCE composite film. This work provides a simple strategy for the construction of single-layer 3D deformable soft actuators.
