▎ 摘　　要

A small quantity of graphene flakes was doped in a ferroelectric liquid crystal (FLC), and the field-induced fenoelectric electro-optic switching was found to be significantly faster in the FLC + graphene hybrid than that of the pure FLC. Further studies revealed that the suspended graphene flakes enhanced the FLC's spontaneous polarization by improving smectic-C ordering resulting from the pi-pi electron stacking, and reduced rotation viscosity by trapping some of the free ions of the FLC media. These effects coherently impacted the FLC-switching phenotnenon, enabling the FLC molecules to switch faster on reversing an external electric field. (C) 2014 ALP Publishing LLC.
