Thermotropic crystals
Did you know?
A liquid crystal phase is thermotropic if its order parameter is determined by temperature. At high temperatures, liquid crystals become an isotropic liquid and at low temperatures, they tend to glassify. In a thermotropic crystal, those phase transitions occur only at temperature extremes; the phase is … Visa mer • Thermochromism • Thermotropic liquid crystals Visa mer • What are Liquid Crystals?
