Abstract
In this work we propose to study the influence of planar surfaces on dynamic processes in liquid crystal. Part of the research will include freestanding films formed by smectic liquid crystals and the analysis of dynamics in this systems, where the dynamic processes are determined by the surface anchoring of the liquid crystal molecules on the liquid crystal-air boundary. We will investigate the importance of intermolecular interactions and the influence of a given surface on the liquid crystalline structure. A novel optical method that enables us to measure the liquid crystal anchoring coefficients at solid polymer surfaces will be used. The alignment abilities of standard substrates and recently discovered aligning photopolymers, self-assembling monolayers and polymeric liquid crystals will be compared. From these results we will deduce the influence of interaction between liquid crystal molecules and the aligning substrate on the experimentally observable parameters that are relevant for the use of liquid crystals in the display industry.
