Abstract

We review our Monte Carlo studies of molecular ordering in nematic liquid crystals with dispersed polymer networks. Starting from the aligning effect of a single fiber, we study different network topographies and investigate regular and random arrays of straight and distorted polymer fibrils. We analyze the aligning ability of rough fibrils, external field-induced switching, and pretransitional ordering. The simulation output is used to calculate selected experimental observables: 2H NMR spectra, capacitance, and intensity of transmitted polarized light.
