Flexible Polymer Dispersed Liquid Crystal Module with Graphene Electrode

Flexible polymer dispersed liquid crystal (PDLC) module based on graphene electrode was presented in this article. We also investigated electromechanical, as well as electro-optical properties of PDLC module with graphene electrodes. Compared to the ITO electrodes, graphene electrodes exhibits higher light transmittance and more stable electromechanical property of under bend test. Due to the excellent mechanical property of graphene electrodes, it is expected that the flexibility of PDLC module could be further enhanced. Meanwhile, with the integration of graphene as the driving electrodes, the threshold voltage V(th) and saturation voltage V(sat) of PDLC module have small change, while the on-state transmittance T(on) is increased by 5%, that may attribute to the high transmittance of the graphene.
