We studied the change in optical, electro-optical and electrical response of liquid crystal (LC) E7 when this room-temperature nematic is mixed with a very small amount of graphene nanoparticles at concentration of 10−3 wt.%. Being nematic nanocomposite material, such graphene-doped LC material is of interest for electro-optics and organic electronics, and the examined properties are of importance for both electro-optical and electrical performance of practical LC devices. Thin planar-oriented films with a thickness of 7 µm of graphene-doped E7 were inspected and their responses were compared to those of films of pure LC E7 measured under identical experimental conditions. Even at this very low level of doping with graphene nanoparticles, one can achieve a considerable positive effect on electrical transport in graphene/E7 nanocomposites, useful for their electro-optic applications.
