Hydrogel Material for Contaminants Removal

  • removal of per- and poly- fluoroalkyl substances (PFAS)
  • environmental contamination and water treatment
  • hydrogel technology


A number of widely-used, environmentally-persistent per- and poly-fluoroalkyl substances (PFAS) – nicknamed “forever chemicals” – are linked to a number of health problems, including cancer. A cost-effective treatment process for PFAS is not currently available, and there is an urgent need to develop novel sorbents with high-capacity, easy regeneration with short equilibration times for efficient PFAS removal.


This invention has developed hydrogel-based microstructures based on functionalized polyethylene glycol diacrylate (PEGDA) for PFAS removal.
