WebbThermotropic and lyotropic liquid crystals consist mostly of organic molecules, although a few minerals are also known. Thermotropic LCs exhibit a phase transition into the LC phase as temperature changes. Lyotropic LCs exhibit phase transitions as a function of both temperature and concentration of molecules in a solvent (typically water). WebbIsotropic liquid transition Most solid materials produce isotropic liquids directly upon melting. However, in some cases one or more intermediate phases are formed (called …
