Phase separation in liquid crystal/gel composites: Role of network elasticity

Research output: Contribution to journal › Article › peer-review

Abstract

Phase separation in gels swollen by nematic solvents is investigated using a time-dependent Ginzburg-Landau model. We demonstrate that elasticity of the polymer network is responsible for a foam-like domain morphology observed in polymer dispersed liquid crystals (PDLCs). Rubber elasticity also prevents domain merger, leading to a coarsening behavior substantially slower than in liquid-liquid demixing. We briefly discuss phase separation in nematic polymer gels, in which operates a novel anchoring mechanism mediated by elastic strain.
