Photonic crystal has been researched in biomimetic science and technology. A cholesteric liquid crystal (CLC) monomer (CBP-RM) is newly synthesized for fabricating chiral photonic crystal (CPC) film. The CPC film is constructed by copolymerization between the CBP-RM and well-known achiral LC reactive mesogen. The helical pitch of the CLC monomer mixtures can be controlled by temperature. After polymerization at selected temperature, the fixed free-standing film is fabricated. The CPC film exhibits the good mechanical, thermal, and chemical properties for various applications. We expect that CPC film can be applied in smart paints, and optical device films.
