Abstract
A trap Including: an inlet configured to receive a fluid conveying nanostructures; ionic liquid configured to trap the nanostructures; and an outlet for the fluid.
Claims7
A method comprising:
- receiving a fluid conveying nanostructures, the nanostructures comprising graphene;
- trapping the nanostructures using ionic liquid, the ionic liquid comprising a room temperature ionic liquid comprising an ionic salt;
- recycling the nanostructures to a source of the nanostructures;
- and
- exhausting the fluid;
- wherein the nanostructures are reversibly trapped by π-π electron system interactions.
