Abstract

This work describes the fabrication of temperature responsive light reflectors deposited on flexible single substrates, the photonic cholesteric liquid crystal system encapsulated by a protective polymer layer generated by photo-enforced stratification. A bendable orange reflector was fabricated by this single application step. Furthermore, a blue shift of 400 nm of an infrared reflecting cholesteric was demonstrated upon increasing the temperature from room temperature to 100 °C. Such reflectors on flexible substrates could be used for the retrofitting of existing windows to save energy and visible reflectors in clothing or other aesthetically-pleasing applications
