Why Graphene Oxide Membranes

  • Highest demonstrated water vapor permeance – less material needed, smaller capex
  • Negligible swelling upon exposure to water or organics – easier manufacturing
  • Stable to harsh chemicals like chlorine – easier cleaning if needed in water applications
  • Not fluorinated therefore no release of PFAs
  • Studies have shown them to be fouling resistant



Application areas include humidification, dehumidification, pervaporation, and gas dehydration among many others.

Vapor-vapor phase separations

  • Air dehumidifiers*
  • Energy recovery ventilators (ERVs)*
  • Fuel cell humidifiers*
  • Gas dehydration (e.g., hydrogen, Co2, natural gas*)
  • Tritiated water recovery*
  • Air dehumidification for more energy efficient air conditioning

Vapor-liquid phase separations

  • Evaporative cooling*
  • Humidifiers
  • Solvent dehydration
