概要

• 論文の詳細を見る

• We theoretically study volume phase transitions of a nematic gel immersed in mixed solvents, consisting of a low molecular weight liquid crystalline molecule (nematogen) and an isotropic solvent. Combining Flory model for an elastic free energy of the nematic gel with Maier-Saupe model for nematic ordering, we calculate the equilibrium swelling of the gel, orientational order parameters, and elongation of the gel as a function of the concentration of nematogens in the mixed solvents. We find an isotropic gel is discontinuously condensed into a nematic state with increasing the concentration of the nematogen. We also discuss swelling behaviors of the gel accompanying a nematic-isotropic phase separation in a bulk phase outside the gel.
