Abstract: | We present results for the effects of a crosslinking agent, cure temperature, and UV flux on the electro‐optical properties of polymer‐dispersed liquid crystal (PDLC) cells. These cells were fabricated using a mixture of a liquid crystal (E8) and an acrylic monomer (CN135). The maximum in the first derivative of the transmission vs. applied, sinusoidal voltage (inflection voltage, Vinf), varies systematically with PDLC formulation and cure‐process conditions. For PDLC cells fabricated with a crosslinking agent (SR295), Vinf increases with increasing the concentration of SR295. However, for cells fabricated without the use of a crosslinking agent, Vinf decreases with increasing the UV flux and decreasing temperature. © 2003 Wiley Periodicals, Inc.
