Claim 9:
10. A method of fabricating a foam, the method comprising:
preparing a slurry of slurry components, the slurry components comprising a freezing agent, a binder, a dispersant, and particles of a first material of the foam;
casting the slurry into a mold to give a shaped slurry; and
freeze-drying the shaped slurry at a temperature in a range of from −60° C. to −30° C. to give the foam comprising the first material,
the foam being free-standing,
the foam comprising a reticulated microstructure and lamellar domains,
the first material being tungsten sulfide (WS2),
the preparing of the slurry comprising vortex mixing and bath sonication of the slurry components,
the freeze-drying comprising freezing the shaped slurry and sublimation of at least a part of the freezing agent,
the freezing agent being deionized water,
the particles of the first material comprising nanoplatelets of the first material, and
the binding agent comprising styrene-butadiene rubber (SBR) and the dispersing agent comprising carboxymethyl cellulose (CMC).
