- Title:Vertical Alignment and Stabilization of Director Pre-Tilt of Nematic Liquid Crystal Doped by Surface Modified Silica Nano-Particles

Abstract: We report a vertical alignment and pretilt control of nematic liquid crystals (NLC) doped by surface modified spherical silica nanoparticles (SNPs). The SNPs have been modified by photoreactive 3-(trimethoxysilyl) propyl methacrylate and homogenously dispersed in NLCs with negative dieleteric anisotropy. The surface modification has been accomplished through the silane coupling reaction to hydroxyl groups on the surface of SNPs [1]. The homogeneous mixture has been prepared by controlling dispersion rate, sonication conditions and processing temperature. The electro-optic (E.O.) cells have been fabricated by using fishbone-patterned pixel electrode. No pretreatment has been performed for the alignment of LC molecules.
