摘要：

Electrooptical properties were studied on a new type of polymer/liquid crystal(LC) composite film composed of a poly(vinyl alcohol) (PVA), LC, and a photocured polymer. The composite films were prepared by casting the PVA/LC emulsion with a mixture of benzylmethacrylate (BzMA) with perfluorooctylethylacrylate (FA-108) followed by photocuring, resulting in a low driving voltage of 19 V-rms, a rapid turn-on time of 0.2 ms, and a rapid turn-off time of 11 ms. The results cannot be entirely explained by the change in droplet shape and size. It was suggested that photocurable monomers polymerized at the interface which caused change in the boundary condition between PVA and the LC.
