Polysulfones have been implemented in a variety of applications, including membrane technology, dielectric capacitors, flame retardant materials, and impact resistant displays. Introducing charged moieties into the polymer repeat unit introduces added functionality, develops new morphological features, improves thermomechanical performance, and expands potential applications (e.g., ion-conducting battery electrolytes). This work reviews recent developments in the preparation of polysulfones that can undergo post-polymerization modification reactions to introduce pendant cations, anions, or zwitterions. The synthesis, subsequent characterization, and processing to form thin film and hollow fiber membranes will be discussed.
