Vertical Alignment of a Nematic Liquid Crystal by Composite Materials Containing Perfluorinated and Siloxane Units

摘要

Here we report on the study of vertical alignment of a nematic liquid crystal due to the segregation between perfluorinated and the polysiloxane groups of a multi-component composite alignment material. The measured surface anchoring energy was found to depend on the relative amount of polysiloxane matrix in the composite material.
