    With the acceleration of industrialization and the continuous growth of the global population, the severe shortage of freshwater resources has become increasingly serio.


    In view of this, Associate Professor Liu Yanan of Hainan University and Professor Marc-Olivier Coppens of University College London (UCL), UK, are influenced by cell membrane structure (including aquaporins with hydrophilic gates for selective transport and hydrophobic channels for low friction with water) Inspired by a vacuum-assisted self-assembly process, a graphene nanomesh (GNM) film was fabricat.


    Preparation and characterization of GNM and CS@GNM

    GNMs with nanopores were synthesized in two ste.

    Wettability, permeability and morphological stability of GNM membranes

    The authors performed a series of contact angle measurements to evaluate the surface wettability of cell membrane-inspired GNM membran.

    Antifouling properties of GNM membranes

    The authors evaluated the antifouling performance of GNM membranes by filtering a series of surfactant-stabilized oil-in-water emulsions prepared from sunflower oil, pump oil, octane, and silicone o.
