We develop functional polymeric adsorbents and hyper-crosslinked networks that use supramolecular motifs and post-synthetic functionalization to remove chemical pollutants (organic dyes, iodine species, and ionic contaminants) from water. Research integrates design of polymer scaffolds (e.g., tosylated hyper-crosslinked polymers), surface functionalization to tune selectivity, and application testing for fast, efficient adsorption and recyclability. Representative publications demonstrate rapid dye removal, iodine capture using halogen-bonding concepts, and scalable HCPs for anionic pollutant removal — highlighting the lab’s materials-centric route to sustainable remediation.
