Why Graphene Oxide Thin Films Are Water Stable
The stability of graphene oxide films in water is crucial to their use as membranes for aqueous filtration and separation applications. That stability is also something of a mystery. In water, the films become negatively charged, so electrostatic repulsions ought to cause the films to disintegrate. Researchers have now shown that the membranes remain stable owing to metal ion contamination (Nat. Chem. 2015, DOI: . . .
