Outline of Final Research Achievements

In this study, we investigated the gelation mechanism of TetraPEG prepolymers in aprotic ionic liquids from the viewpoints of solution chemistry (i.e., reaction kinetics and acid-base equilibrium in ionic liquid system). The TetraPEG ion gels were characterized in terms of (1) gelation kinetic constant and reaction effeciency of the cross-end coupling reaction in this system, (2) mechanical properties. In addition, the ion gels were applied to CO2 separation membranes.
