Abstract
Films were formed by coating hydroxypropyl cellulose (HPC) or ethyl cellulo se (EC) with different kinds of solvents at high coating speeds and thin co ating thicknesses. These films were used as alignment layers for liquid cry stals. Atomic force microscopy (AFM) and polarizing optical microscopy (POM ) were used to identify the banded texture structure of the films. The alig nments of a nematic liquid crystal 5CB droplet on those films were observed by POM. Further, a novel cycle disclination line was recorded and studied. (C) 2001 John Wiley & Sons, Inc.
