Webb26 jan. 2010 · Both main classes of liquid crystals, thermotropics and lyotropics, have been used successfully. This reveals an aligning mechanism resulting from the liquid crystallinity per se, independent of specific molecular structures, although these can affect the degree of order and the quality of the tube dispersion. WebbThe liquid crystal phases of a thermotropic material are generated by changes in temperature (see Chapter 3). However, lyotropic liquid crystal phases are formed on the …
