Spinodal decomposition of liquid crystalline mixtures. - 150 p.

Liquid crystalline materials represent a state of matter distinct from the gas, liquid or solid state. Liquid crystals are characterized by an intermediate degree of molecular order. They lack the full three dimensional symmetry of a crystalline phase but they are more ordered than simple liquids. The development of a new type of flat panel display along with the need to improve the processing of liquid crystalline polymers has led to an interest in the phase separation kinetics and morphology development in mixtures containing nematic liquid crystals. In this work, three goals are accomplished. First, the validity of a lattice model for mixtures of rigid and flexible molecules is rigorously tested against experimental data. Second, new general criteria for the stability of mixtures containing nematics are developed. Finally, a theory of the dynamics of phase separation is developed within the framework of nonequilibrium thermodynamics. The theory is tested against experimental results available from small angle light scattering and polarizing optical microscopy.Subjects--Topical Terms:
