1. A method of fabricating a graphene oxide film, comprising:
(a) suspending a graphene oxide in a first solvent to form a graphene oxide suspension;
(b) dispersing the graphene oxide suspension in a second solvent to form a graphene oxide dispersion;
(c) reducing the graphene oxide dispersion;
(d) filtering the graphene oxide dispersion through a membrane to form a graphene oxide film on the membrane; and
(e) freeze-casting the graphene oxide film on the membrane, wherein the graphene oxide film has a tensile strength of about 9 MPa to about 36 MPa.
