The development of novel hydrogels with high biocompatibility is a vital and active topic of study. Here, we used a facile polycondensation approach to develop multifunctional poly (ether sulfone) (PES)-based hydrogels with diverse functional groups (−SO3Na, −COONa, −OH, and − NH2), as indicated by flourier transformed infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS). The chemical structure of the PES-based hydrogels could be modulated by monomer selection and post-treatment, resulting in a wide range of biomolecul...
