Outline of Final Research Achievements

In materials science and technology, it is sometimes important to control the anisotropic properties of materials. Among the methods for preparing anisotropic gels, dialysis-induced gelation has the advantage that the balance between the energetic and entropic effects is automatically obtained by self-organization and the gel formation which is closely related to the appearance of anisotropy, can be analyzed by means of nonequilibrium thermodynamics. In the present study we clarified the relationship between preparation condition, gelation dynamics and gelation mechanism experimentally and theoretically and applied it to a variety of practical processes.
