摘要：

A tunable electro-optical switching is reported for single-layered polymer-dispersed liquid crystal (PDLC) films, controlled by the film thickness Thin planar film of two-dimensional layer of thickness continuously varying from a few micrometers to several tens of micrometers is examined. The wedge-confined PDLC single layer contains E7 liquid-crystal microdroplets dispersed in a transparent polymer matrix of NOA65. The diameters of the droplets with a linear-gradient size distribution along the wedge slope reach several tens of micrometers, defined by the wedge geometry of the film. The electro-optical switching of the single-layered PDLC film is linked to its microstructure and droplet organization.
