Impermeability properties of Biphenylene Carbon (BPC) membranes
Biphenylene carbon (BPC) is a graphene-like porous carbon allotrope. Due its 2D topology and single atom thickness (planar sheet), BPC can, in principle, work as a membrane impermeable to gases. In this work, through fully atomistic molecular dynamics simulations we show that BPC membranes are indeed impermeable to oxygen, argon and carbon dioxide molecules.
