Electrically switchable birefringent self-assembled nanocomposites: ferroelectric liquid crystal doped with the multiwall carbon nanotubes

Popis výsledku v původním jazyce

Functional nanocomposites are designed via doping ferroelectric liquid crystal (FLC) matrix by 0.03wt% and 0.1wt% of functionalized multiwall carbon nanotubes (MWCNTs). Mesomorphic, optical and electro-optic behaviour of resulting nanocomposites were studied. FLC material demonstrates electrically switchable birefringence colours under applied electric field at different temperatures. No considerable perturbation of FLC smectic order has been observed in dependence of MWCNTs doping. However, the MWCNT doping strongly modifies the optical contrast, birefringence, transmission and contrast ratio of the FLC material. Furthermore, doping by MWCNTs leads to generation of new colours in the nanocomposite systems and also effectively reduce the driving voltage for the colour appearance. Such electrically switchable birefringent MWCNTs/FLC nanocomposites can be effectively utilised for the field-sequential colour displays, FLC switches, optoelectronic and photonics devices.
