Atom-thin membranes for high-performance separation
We create the worlds best membrane out of the noble-price-winning material graphene. Our membranes can contribute to solving the water and climate crisis by providing cheap drinking water and capturing industrial CO2-emissions and more.
Graphene is with its atomic thinness at the physical limit of thinness (< 1 nm, ca. 1/100’000th of the thickness of a human hair) and simultaneously impermeable to any liquid or gas in its pristine form. If perforated precisely with a high density of pores, this material promises to be the ultimate membrane. We are developing a novel method of perforating graphene precisely with controlled, high-density of pores to achieve high membrane porosity (ca. 100 billion pores on one cm2 membrane area). We study gas and liquid transport across such fabricated membranes to understand the mechanisms of gas separation and liquid filtration that dominate the performance of these nanoporous membranes. The gathered knowledge of membrane fabrication and mass transport characterization will enable the development of novel technologies for applications in liquid purification and gas separation.
