Abstract
Polymer network liquid crystal (PNLC) films were prepared from poly(vi nyl alcohol) (PVA) and E44 using an emulsion technique. Effect of the wavelength of incident light in addition to the input electric field h as been studied. It was found that the morphology of the composite fil m mainly depends on the film composition. The transmittance of the pow ered him increased, rapidly at high and smoothly at low applied voltag e, with increasing incident wavelength, however, it was slightly decre ased for unpowered film.
