Abstract:
A blue phase liquid crystal material includes a liquid crystal host, a chiral reagent and a stable polymer. The chiral reagent is R811. The stable polymer is formed by photo-polymerizing a first monomer and a second monomer. The first monomer is 2-ethylhexyl acrylate (2-EHA), and the second monomer is 2-methyl-1,4-bis{4-[3(-acrylate)propoxyl]benzoicacid}phenylester (PTPTP). The blue phase liquid crystal material has a blue phase temperature range widened to an extremely low temperature. A blue phase liquid crystal composition and a method for manufacturing the blue phase liquid crystal material by using the blue phase liquid crystal composition are also provided.
