Abstract
PURPOSE: A novel liquid crystal of polysaccharide that is composed of a polysaccharide that has β-1,3-D-glycoside linkage as the major chain and a helix structure, thus showing optical anisotropy and stripe pattern with a regular distance on the observation with a polarization microscope and having a cholesteric color.
CONSTITUTION: A polysaccharide that has β-1,3-D-glycoside linkages as the major chain and a helix structure, preferably schizophyllan or scleroglucan, is dissolved in such a solvent as the helix structure is kept therein, preferably in water at a lower temperature than its boiling point and the resultant solution is stood, until the solution converts into a cholestric liquid crystal, to give the objective polysaccharide liquid crystal. This cholesteric liquid crystal state is confirmed by following observations: the solution is opticaly anisotropic, because light remarkably transmits through the solution, when laser is irradiated; a stripe pattern of a regular interval appears, when the observation is continued with a polarization microscope and interference rings caused by Bragg's reflection are observed.
