An Ion Gel is a relatively new material where an ionic conducting liquid is immobilized inside a polymer matrix. This allows the design of unique materials with high ionic conductivity combined with the easy handling properties of the solid state. To create an ion gel, a block copolymer is polymerized along with an ionic liquid

Ionic liquid

An ionic liquid is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as . While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ILs are largely made...

 so that self-assembled nanostructures where the ions are selectively soluble.

Ion gels have been successfully used as gate insulators for field effect transistors which reduces the voltage requirements.
