Abstract
A process for the production of nano-structures is presented, involving providing a graphite flake comprising graphene layers; intercalating the graphite flake to form a graphite intercalation compound exhibiting Stage I, II or III intercalation; and exfoliating the graphite intercalation compound under conditions such that a plurality of individual graphene layers are separated from the graphite intercalation compound.
Claims13
A process for the production of structures which are, on average, no greater than about 1000 nanometers in at least one dimension, comprising providing a graphite flake comprising graphene layers;
- intercalating the graphite flake to form a graphite intercalation compound exhibiting Stage I, II or III intercalation;
- and exfoliating the graphite intercalation compound by exposing the graphite intercalation compound to a temperature of at least about 1300° C. such that a plurality of individual graphene layers are separated from the graphite intercalation compound, wherein the graphite intercalation compound is brought from a temperature at which it is stable to a temperature of at least about 1300° C. within a period of no more than about 1 second.
