Composite ionic conductors based on homoionic montmorillonites (2:1 charged layers silicates containing metal ions in their interlayer space) cinteracted with poly(ethylene oxide) exhibit enhanced condcutivity between silicate layers (see figure). The presence of tunnels in the intercalated polymer–salt complex is thought to facilitate intracrystalline ion mobility.
