Alignment Layer of Liquid Crystal Using Plant-Based Isoeugenol-Substituted Polystyrene

Spatial and Orientational Control of Liquid Crystal Alignment Using a Surface Localized Polymer Layer

Liquid-crystal diffraction gratings using polarization holography alignment techniques

A method of patterning surfaces for liquid-crystal alignment using a polarization holography exposure on a linear photopolymerizable polymer alignment layer is demonstrated. Three configurations are demonstrated which include registered planar-periodic surface boundary conditions on both surfaces true polarization gratings , planar-periodic and uniform planary surface boundary conditions, and p...

Photopatterning of Liquid Crystal Alignment Cells

Surface Dipole Control of Liquid Crystal Alignment.

Detailed understanding and control of the intermolecular forces that govern molecular assembly are necessary to engineer structure and function at the nanoscale. Liquid crystal (LC) assembly is exceptionally sensitive to surface properties, capable of transducing nanoscale intermolecular interactions into a macroscopic optical readout. Self-assembled monolayers (SAMs) modify surface interaction...

The Effect of Siox Alignment Layer Thickness on the Switching of Smc* Bistable Liquid Crystal Devices

SiO x alignment layers have been shown to allow defect-free SmC ‫ء‬ devices with near optimum bistable orientation of the director. In this paper we investigate the effect of the thickness of this type of alignment layer on the required amplitude of an applied voltage pulse to cause bistable switching. The results of an experimental investigation and simple model are presented. We find that for...
