A (polymer network/nematic liquid crystal/chiral dopant) composite was developed. The composite was prepared from photopolymerization of (liquid crystal monomer of nematic diacrylate/nematic liquid crystal/chiral dopant/photoinitiator) mixture. The bandwidth of the selective reflection spectrum of the chiral nematic (N*) phase was found to become wider and narrower with increasing and decreasing temperature respectively. The composites were shown to have prospects for application in thermally bandwidth-controllable reflective polarizers or thermally sensitive infrared sensors.
