Effect of Ordering on Spinodal Decomposition of Liquid-Crystal/Polymer Mixtures



A M. Lapena, S C. Glotzer, Stephen A. Langer, A J. Liu


Partially phase-separated liquid-crystal/polymer dispersions display highly fibrillar domain morphologies that are dramatically different from the typical structure found in isotropic mixtures. To explain this, we explore the coupling between phase ordering kinetics and phase separation kinetics when such a mixture phase separates into a nematic phase rich in liquid crystal coexisting with an isotropic phase rich in polymer. We find that phase ordering can lead to fibrillar networks of the minority polymer-rich phase.
