Dielectric studies and nano-molecular self assembly of lyotropic chromonic liquid crystalline phases

Author(s): T.N.Govindaiah

In the present work, our investigation is to study the optical and dielectric properties of the binary mixture of Abietic acid in Ethylene glycol which exhibits a very interesting liquid crystalline biphasic region of aggregated columnar (C+I) and columnar (C) phases sequentially when the specimen cooled from isotropic phase. These phases have been characterized by using microscopic and optical anisotropic technique. The temperature variations of dielectric parameters have also been discussed. Xray studies are supported to calculate the nano-aggregated grain size of the molecules.
