Paper Abstract

We present in this paper the results of our investigations concerning the effect of different types of self-assembled (chemisorbed) monolayers on the alignment of liquid crystals. While the hydrophobic monolayers tend to align liquid crystals homeotropically (molecules perpendicular to the surface), the hydrophilic monolayers, in general, lead to a planar orientation. The quality of alignment is found to depend on the degree of hydrophilicity as determined from contact angle measurements.
