Paper Abstract

The molecular anchoring strength for the liquid crystal E7 (EM Chemicals) confined to spherical cavities dispersed in the polyurethane TU5OA (CONAP) is measured. The anchoring strength values result from a study of the radial-to-axial configuration transition when perpendicular anchoring conditions exist at the polymer/liquid crystal interface. This transition is also a function of droplet radius, temperature, and the strength of any external fields present. A study of field-induced configuration transitions provides values for the reduced local electric fields inside droplets. Computer simulated pictures of nematic droplets are formed to identify director configurations.
