摘要：

Cholesteric liquid crystal (CLC) film with adjustable high reflection wavelength of light response is prepared by refilling the light-response CLC system into the polymer network with broadband reflection memory effect, which is the washing out/refilling method. The film is reusable with some treatment. The adjustable range of high reflection wavelengths in the near-infrared region and visible region were 1270-1750 nm and 640-1110 nm, respectively. In addition, a highly reflective film with broadband reflection has been successfully prepared in the wavelength range of 1238-1826 nm, and the waveband can reach 588 nm. This research has excellent application prospects in building energy conservation, radiation protection, aerospace and other fields.
