Recent works on the syntheses and applications of poly(ionic liquid)s are reviewed.

The preparation of dispersions of 2D materials in various solvents, as well as the characterization methods, is critically reviewed.

2D materials for the electrochemical oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, and CO₂reduction are critically reviewed.

Surfactants based on imidazolium ionic liquids (ILs), including polymerizable surfactant ILs, have been synthesized and used to stabilize polymerizable microemulsions useful for producing polymer nanoparticles, gels, and open-cell porous materials.
