The synthesis and application of poly(ionic liquid)s functional materials

Poly(ionic liquid)s are ionic polymers containing ionic liquid anion and cation structures in polymer repeating units. Poly(ionic liquid)s possess the physical and chemical properties of small ionic liquid molecules (structural diversity, adjustable solubility, chemical/thermal stability, conductivity, etc .) and the mechanical properties and processability of polymers, which makes it possible to apply in conductive materials, intelligent response materials, biomedical materials and other fields. This article mainly reviews the synthesis methods of poly(ionic liquid)s and their potential applications as functional materials in the fields of energy devices, smart response devices and antibacterial materials.
