Outline of Final Research Achievements |
We have prepared the optically anisotropic gel by using the method in which cellulose solution was only contacted with ion-exchange resins. We also prepared another optically anisotropic cellulose gel under electric field with ion exchange membrane. The relation between molecular network formation and deionization is discussed. Optically anisotropic cellulose gels were successfully prepared from cellulose in sodium hydroxide aqueous solutions under electric field with ion exchange membrane. The gel was formed on the membrane surface of the anode side, although it was not formed on the cathode side. This result suggested that the deionization from the solution was one of the important factors in the formation of the optical anisotropic gel. In the rheological measurements, the storage modulus of cellulose solutions increased with time of applying electric field to them. It was indicated that deionization and molecular network formation proceed correlatively.
