英文摘要	A phototunable polymer-stabilised liquid crystal film reflecting both right- and left-circularly polarised light has been successfully fabricated by a washout/refill method. The film was obtained by prefabricating the polymer network with a left-handed helical structure and then refilling a light-driven chiral nematic liquid crystal with a right-handed helical structure into the network. Interestingly, the reflection wavelength and the reflectivity properties can be precisely tuned by UV-light irradiation. A hyper-reflective notch, the reflectivity of which approaches 100%, was achieved in a layer when the pitch lengths of the two opposite helical structures are almost the same. Moreover, their original state can be properly returned by visible-light irradiation.; Sino-American Cooperative Project of Chinese Ministry of Science and Technology [2013DFB50340]; National Science Foundation of China [51173155]; Major Project of Beijing Science & Technology Program [Z121100006512002]; National Natural Science Foundation of China [51103010]; Doctoral Fund of Chinese Ministry of Education [20120001130005]; SCI(E); ARTICLE; hqzhang@ysu.edu.cn; 8; 1120-1123; 42
