What are #Graphene membranes?
Graphene oxide membranes are made by piling layers of graphene oxide (a derivative of graphene) on top of each other. The stacks have a similar structure to nacre (mother of pearl)
They are capable of forming a perfect barrier to liquids and gases. They can even block helium, the hardest gas to block

Graphene's love affair with water
G
Graphene oxide has both hydrophobic and hydrophilic properties. When sheets of graphene oxide are arranged in such a way, they create channels allowing water to pass through
How can graphene be used in membrane applications?
Using graphene in food and pharmaceutical packaging can stop the transfer of oxygen and water, keeping goods fresher for longer
By 2025 the UN predicts that 14% of the world's population will experience water scarcity
Every day 900 children die across the world from diarrhoeal diseases caused by dirty water and poor sanitation
Graphene has the potential to provide clean drinking water to millions of people
Carbon dioxide removal from power station flue gases isn't yet done on any scale. Graphene could be the answer to making this economically viable
