Electro-responsive 1-D nanomaterial driven broad-band reflection in chiral nematic liquid crystals

Abstract

A controllable and reversible broad-band reflector can be obtained by virtue of the response of one-dimensional (1-D) nanomaterials in chiral nematic liquid crystalline media to an external electric field. The colour switching originated from the electro-responsive 1-D nanomaterials and the responsive mechanism was discussed based on the relationship between the pitch distribution and the alignment of nanomaterials.
