Volume Phase Transition of Polymeric Gel.

概要

It has been shown that some polymeric gels undergo continuous or discontinuous volume changes depending on external conditions (e. g., temperature, pH and solvent concentration). Therefore, the gels are expected to be applied as a size-selective extraction solvent and other functional materials. To apply the gel as an extractor or other functional materials, we should study volume changes of the gel in solvent mixtures and concentrations inside and outside the gel. Furthermore, fundamental knowledge of mesh sizes of gel network and interactions between network and solvents have become very important. Therefore, fundamental studies and applications of polymeric gel are reviewed: Thermodynamic models for polymeric gels are reviewed. Finally, pressure-dependent phase transitions in polymeric gels are briefly reviewed and discussed.
