Ionic Liquids are salts which are liquid at room temperature. Their excellent ion conductivity makes them highly attractive for electrochemical applications such as fuel cells or various organic electronic devices. For many applications, however, it would be much easier to handle ionic liquids in a solid state, in form of a membrane. The aim of this thesis was to produce polymerised membranes from ionic liquids via initiated Chemical Vapour Deposition and to characterise the obtained films with regard to their polymerisation and conductivity.

The conducted experiments show that the obtained membranes were partly polymerised and are sufficiently conductive to be used for the desired electrochemical applications. Furthermore, by tuning various parameters a good recipe for the polymerisation process could be found.
