NANOCOMPOSITE MATERIALS WITH CONTROLLED ION MOBILITY

The intercalation or entrapment of oxyethylene compounds, crown ethers, and poly(ethylene oxide) into inorganic hosts provides the opportunity to design and prepare nanocomposite materials useful for membrane and solid electrolyte applications. Crown ethers incorporated into the membranes produced by intercalation can act as ion-selective sensors. The field is reviewed and several recently developed applications described.
