Nematic mesophase
The simplest liquid crystalline phase that is formed by spherical micelles is the 'micellar cubic', denoted by the symbol I1. This is a highly viscous, optically isotropic phase in which the micelles are arranged on a cubic lattice. Prior to becoming macroscopic liquid crystals, tactoids are formed, which are liquid crystal microdomains in an isotrophic phase. At higher amphiphile concentrations the micelles fuse to form cylindrical aggregates of indefinite length, and these cylinders are arra… WebNov 9, 2010 · Comparative investigations of the thermo-optical, thermotropic, and thermo-morphologic properties of aligned and non-aligned textures in the nematic mesophase …
