SIMULATION ON THE KINETIC PROCESS IN POLYMER-DISPERSED LIQUID-CRYSTALS - EFFECTS OF VARIOUS CONCENTRATION OF LIQUID-CRYSTALS

We developed a dynamical model for the formation in polymer-dispersed liquid crystals. The model has the key feature that the mechanism of p olymerization obeys the radical addition polymerization and the moveme nt of molecules is allowed by Kawasaki dynamics(1). Monte Carlo comput er simulations on this model show that the time evolutions of the stru cture factors exhibits dynamical self-similarity and the mean cluster size of liquid crystals has a peaking behavior until the phase separat ion is pinned(2). In the study, the simulation was performed with vari ous concentration of liquid crystals. The mean cluster size of liquid crystal increases as the concentration of liquid crystals increases. W e found a relation between the mean cluster size and the concentration of liquid crystals. The simulation results are well consistent with r ecent experimental observations.
