Liquid Crystal Systems as Machinery (I) : A New Image for LC System as Molecular Machinery

Abstract

In a machinery model for liquid crystal system, molecules existing in neighboring layers are working harmonically as rotor-bearing system. Molecules may be rigid or clastic depending on its stiffness. Their librational motion induces catastrophic molecular reorientation at the critical speed, i.e. the phase change. This critical speed is sensitive to the molecular conformation and configuration. Influences of the rotational moment of the molecules, weight balance and the position of the weight center to the phase behavior are discussed in this paper.
