Can Spin Models Reproduce or Predict Experimental Results in PDLC?

Abstract

Lattice spin models are employed to study polymer dispersed liquid crystals (PDLC). We calculate polarized light textures and Deuterium NMR lineshapes from Monte Carlo computer simulations of model nematic droplets that mimic PDLC systems with radial, toroidal and bipolar boundary conditions. We also present microscopic properties such as order parameters across the sample obtained from the simulations. Our investigations of the PDLC systems include various temperatures and external applied fields both with positive and negative susceptivity anisotropy.
