In this presentation we will review our recent activities in the synthesis, characterization and applications of new ionic polymers. First, several examples on the synthesis of poly(ionic liquid)s such as polyDADMATFSI will be shown. The application of those poly(ionic liquid)s in batteries will be explained showing examples of its use as polymer electrolytes in lithium and sodium batteries as well as polymer binders in high voltage cathodes.
Second, a novel family of multifunctional deep eutectic monomers based on polyphenols and the corresponding polymers will be discussed. Phenolic chemistry allows modulating molecular interactions tuning the ionic polymer properties from soft adhesive to tough materials. Pyrogallol and hydrocaffeic acid-derived ionic polymers showed outstanding adhesiveness. Additionally, phenolic polymeric deep eutectic solvents (polyDES) featured metal complexation ability, antibacterial properties, and fast processability by digital light 3D printing.
