Lockheed Martin has been awarded a patent for Perforene™
material, a molecular filtration solution designed to meet the growing global
demand for potable water.
The Perforene material works by removing sodium, chlorine and other ions
from sea water and other sources.
“Access to clean drinking water is going to become more critical as the global population continues to grow, and we believe that this simple and affordable solution will be a game-changer for the industry,” said Dr. Ray O. Johnson, senior vice president and chief technology officer of Lockheed Martin. “The Perforene filtration solution is just one example of Lockheed Martin’s efforts to apply some of the advanced materials that we have developed for our core markets, including aircraft and spacecraft, to global environmental and economic challenges.”
The Perforene membrane was developed by placing holes that are one
nanometer or less in a graphene membrane. These holes are small enough to trap
the ions while dramatically improving the flow-through of water molecules,
reducing clogging and pressure on the membrane.
At only one atom thick, graphene is both strong and durable, making it more
effective at sea water desalination at a fraction of the cost of
industry-standard reverse osmosis systems.
In addition to desalination, the Perforene membrane can be tailored to
other applications, including capturing minerals, through the selection of the
size of hole placed in the material to filter or capture a specific size
particle of interest. Lockheed Martin has also been developing processes that
will allow the material to be produced at scale.
The company is currently seeking commercialization partners.
The patent was awarded by the United States Patent and Trademark Office.
