Abstract
Holographically-formed Polymer Dispersed Liquid Crystals (H-PDLCs) are electro-optic devices containing alternating planar layers of polymer and liquid crystal droplets. Here, we investigate the effects of patterned polymer layers on the liquid crystal alignment. Three types of polymers were investigated: urethane resin, Poly Tetra Fluoro Ethylene (PTFE) and Poly Methyl Methacrylate (PMMA). Nanopatterns of the form of square grids were formed on the polymer using the MTS Nano-Indenter in the scratch mode. Liquid crystal deposition on these structures showed unique alignment effects at the polymer interface. The polymers were examined under the Atomic Force Microscope and alignment of the liquid crystals was observed by Polarizing Optical Microscopy.
