2021-049: Highly Robust Laser Induced Graphene (LIG) Composite Membrane with Stable Macroporous Structure for Water Treatment


A scalable method of producing electrically conductive Laser Induced Graphene (LiG) Composite Ultrafiltration (UF) membranes.

The technology produces UF membranes with higher separation and reduced fouling properties when compared to commercially available UF membranes. This method also permits easy tuning of the UF membrane’s permeation level, allowing for more diverse applications. The technology is roll-to-roll compatible permitting high scalability and low cost production.

Market Applications:

  • Removal of particulates and macromolecules from raw water
  • Dialysis and other blood treatments
  • Dairy manufacture
  • Enzyme recovery
  • Desalting and solvent-exchange of proteins

Intellectual Property:

  • U.S. Provisional Patent 63/310,458 was filed on Feb. 15, 2022
