MIT researchers have developed a lightweight polymer film that is nearly impenetrable to gas molecules, raising the possibility that it could be used as a protective coating to prevent solar cells and ...

What is the difference between permeable and impermeable surfaces? Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the ...

The ability of a nanomaterial to prevent the passage of gases or liquids is known as impermeability. In the realm of graphene, achieving impermeability could open up a host of transformative ...
