One basic method for the preparation of Polymer Dispersed Liquid Crystal (PDLC) films is the formation of microdroplets of liquid crystals (LCs) in a polymer matrix by a phase separation process. This can be achieved by radiation-initiated polymerization of a mixture including polymer precursors and LCs. The PDLC films used in this study were prepared by two different methods: Electron Beam (EB) or Ultraviolet (UV) curing. The electro-optical properties of the obtained PDLC-films based on a selected representative composition were investigated as a function of the chosen radiation. The transmission versus voltage curves exhibit a good reproducibility and a strong dependence on the curing conditions for samples prepared in the same experimental conditions. The evaluation of the electro-optical behavior indicates remarkable differences between EB- and UV-cured samples. The results are discussed in terms of off-/on-state transmission values and threshold voltage.
