Abstract

Graphene quantum dots (GQDs)-doped PEDOT:PSS composite layers were utilized to align liquid crystals (LCs) via an ion-beam (IB)-spurting pre-treatment process. LCs were homogeneously aligned between sandwiched GQDs/PEDOT:PSS composite thin layers, and the alignment of LCs was found to be affected by both the quantity of doped GQDs and IBspurting intensity. Competitive electro-optical switching properties and non-residual DC performance of the cell equipped with GQDs/PEDOT:PSS composite alignment layers were obtained because of the enhanced field effect and charge transport induced by doped GQDs. Notably, using IBspurted GQDs/PEDOT:PSS layers as alignment layers for next generation high-performance liquid crystal display (LCD) is promising.
