Fund Project: The authors would like to express their gratitude for the financial support from National Natural Science foundation (No. 20674005), Major project of Ministry Education of the People's Republic of China (No. 104187) and Doctoral Fund of Ministry of Education of the People's Republic of China (No. 20050425850).

A (polymer network/liquid crystal/chiral dopants) composite exhibiting a temperature-sensing switch of infrared spectrum has been developed. Because of the different change of the chiral dopant in the helical twisting power and the anchoring effect of the polymer network, the polymer stabilized liquid crystal (PSLC) films, of which the bandwidth of the selective reflection spectra increased with changing temperature, were obtained.
- Polymer stabilized liquid crystal,
- Thermally induced inversion helical sense,
- Anchoring effect
