The CLCP/CNT composite film exhibited a rapid and reversible deformation under
alternate irradiation by UV and visible light (Fig. 6). This actuation is derived from
the structure change in the composite film, which results from the photoisomerization of the azobenzene moieties. Compared to the CLCPs prepared by

experimental setup. (c) Photographs of the CLCP fiber that exhibits photoinduced bending and
unbending behavior upon irradiation with UV light (100 mW cm
