Dynamic Anchoring of Nematic Liquid Crystals by Flowing Oil

R. Pelcovits, Department of Physics, Brown UniversityG. Crawford, School of Science, Notre Dame University

We are using the unique optical properties of nematic liquid crystals to probe the “dynamic anchoring” of the surface of a nematic microwell by oil flowing above. Understanding the interaction between the oil and nematic may provide a novel wayto construct a petroleum field sensor as well as shed light on fundamental liquidcrystal physics.
