3D Printable Polymer Electrolytes for Ionic Conduction based on Protic Ionic Liquids.

A range of protic ionic liquids (PILs) based on tri-n-alkylammonium cations and mesylate/triflate anions were incorporated into a polymer matrix to form ionogels (IGs). These systems were investigated for their thermal and electrochemical behaviour, as well as under the aspect of ion motion via PFG-NMR. The ionic conductivities of the ILs/IGs are in the range of 10-10 S/cm at elevated temperatures and the diffusion coefficients are around 10 m s.
