Abstract

Abstract:

The thermal stability and electrically responsive ability of composite material systems consist of polymer-stabilized blue phase(PSBP) and multi-wall carbon nanotubes(MWNTs) in different size were studied. The threshold voltages of electric field-induced broadening of reflection spectra can be greatly decreased by doping MWNTs, and it is found that the effect is closely related to the size of MWNTs. The threshold electric field strength is successfully decreased to about 0.1 V/μm in the MWNTs doped PSBP liquid crystalline photonic crystal, and the bandwidth is broadened from 20 nm to 310 nm under electric field with 1.3 V/μm. The materials are promising to be applied in areas of reflective-mode displays or tunable optical filters.

Key words: liquid crystal, blue phase, polymer-stabilized blue phase, carbon nanotube, electrically responsive property
