A new understanding of the physics of conductive materials has been uncovered by scientists observing the unusual movement of electrons in graphene.
In this video we explain what graphene membranes are.
Membranes can be made from graphene oxide, which is a form of graphene. Learn how the graphene oxide flakes stack together to form a laminate which forms a small spaces capable of blocking gases molecules including the smallest of gas molecules, helium.
Treatments can be added to block gases or liquids which opens multiple possibilities including clean water processing, improved anti-corrosion paint and smart food packaging.
