Phys. Rev. Lett. 100, 117801 (2008) [4 pages]In Situ Observation of Fringing-Field-Induced Phase Separation in a Liquid-Crystal–Monomer MixtureReceived 31 July 2007; published 20 March 2008 Fringing-field-induced phase separation dynamics in liquid-crystal–(LC-)monomer mixtures is investigated via a microscope. At a low LC concentration, the fringing field converts the randomly dispersed LC droplets to an ordered droplet array, while at a high LC concentration the fringing field converts the amorphous LC-monomer system to a composite film. Because the LC and monomer are immiscible, the converted morphologies are stable even after the voltage is removed. Using the fringing field-induced phase separation, it is possible to prepare different polymer-dispersed LC morphologies. © 2008 The American Physical Society URL:
