Ionic liquids are considered to be quite promising for creating effective fuel cells, sensors, super capacitors, etc. due to their high ionic conductivity and thermal stability, as well as low pressure of saturated vapours and non-flammability. At the same time, an ionic liquid can be used both as a dopant to the polymer matrix and for the synthesis of a polymerized ionic liquid which, in its turn, is itself a polymer matrix. We have applied methods of fine organic synthesis and radical polymerization to synthesize proton ionic liquids and polymerized ionic liquids. Proton ionic liquids were obtained using trietiamine salts with various acids [1], derivatives of N,Nvinylimidazole, as well as sulphonates of dialkylsubstituted imidazoles, which made it possible for zwitter-ions to be formed with Branstead acids. Polymerized ionic liquids were synthesized by doping polymers, polybenzoimidazole derivatives, with low-temperature trethanolamine-based ionic liquids at lowered temperature under inert gas atmosphere. The second route was via monomers on the basis of a substituted imidazole followed by polymerization by the vinyl group [2] using the method of radical polymerization in the block. Another approach was to obtain a linear polymer based on the zwitter-ion of 1,3-substituted imidazile followed by doping with a strong acid.

Compounds based on zwitter-ions of vinilamidazole were found to be mainly in the glassy state (viscous oil-like liquids). Ionic liquids based on triethanolamine pass into the metastable state via the crystallization-melting process. Polymers based on imidazole derivatives normally exhibit only the glassy state.
