  • Lyotropic chromonic liquid crystal composition, method for manufacture of lyotropic chromonic liquid crystal coating film, and lyotropic chromonic liquid crystal coating film manufactured thereby
    Patent number: 8580143
    Abstract: The present invention relates to a lyotropic chromonic liquid crystal composition, a method for manufacturing a lyotropic chromonic liquid crystal coating film and a lyotropic chromonic liquid crystal coating film manufactured thereby. The lyotropic chromonic liquid crystal composition of the present invention includes chromonic liquid crystal compounds and monomers each having opposing acid-base properties. Use of the lyotropic chromonic liquid crystal composition in the formation of optical films leads to improvements in electrical and optical properties such as mechanical strength, an insulating characteristic and a refractive index.
