Abstract
Polymer-dispersed liquid crystal (PDLC) films are useful in light control applications because they can be switched electrically between light scattering and transparent states. The light scattering effectiveness of a film is intimately related to the size-distribution of the liquid crystal droplets and varies with the wavelength of light. The authors have prepared PDLC films with several droplet sizes and size-distributions, some of which exhibit a polydispersity of droplet sizes. Compared with films characterized by a standard or monodisperse droplet size distribution, polydisperse films exhibit enhanced light scattering and appear well suited for a variety of applications where extended or tuned-wavelength-range light-scattering properties are important.
