제목 Automatic vertical alignment of liquid crystal medium by photopolymerization of amphiphile monomer with polyhedral oligmeric silsesquioxane
초록 Lecithins, silanes, or nano-materials have been introduced into the host nematic (N) liquid crystal (LC) media for the automatic vertical alignment (VA) of LC, but these nano-materials create several problems such as aggregation with themselves, poor compatibility and interaction with host LCs. To overcome these drawbacks, a photo-polymerizable itaconic acid-based amphiphile (abbreviated as Ita3C12) is designed and synthesized for the automatic formation of VA. Ita3C12-based VA was stabilized by the photo-polymerization with methacryl polyhedral oligomeric silsesquioxane (MAPOSS) cross-linkers. The photo-polymerized Ita3C12-based VA layer showed the strong surface anchoring energy without generating any light scattering. This work was supported by the BRL 2015042417, MOTIE/KDRC 10051334, Mid-Career Researcher Program (2016R1A2B2011041), and BK21 Plus program of Korea.
