Graphene is called a "magic material" with its unique mechanical and electrical characteristics, but its interaction with water is confusing: the surface of graphene repels water, but the capillary channel of the graphene film immersed in water allows water to penetrate quickly .

The ability of graphene oxide to screen out nanoparticles, organic molecules and inorganic salts has long been proven, but to this day it is still difficult to be used to filter ordinary salt, because the latter has smaller particles and higher requirements for the fineness of the screen.

▲ Scientists compared graphene screens with existing desalination membrane equipment for testing.
