High-performance graphene nanomesh filtration membranes inspired by cell walls

Graphene-based membranes have attracted considerable attention as promising candidates for new filtration technologies for filtering out nanoparticles, organic molecules, and even small inorganic salt ions. Putting a nature-inspired spin on the fabrication of high-performance graphene membranes for tricky oil/water separations - even in stable emulsions - researchers have demonstrated a graphene nanomesh membrane that possessed high hydrophilicity, super-oleophobicity and low oil adhesion underwater.
