Classification: CPC C  B | IPC B  C

Claim 9:
10. A method of fabricating a hybrid boron nitride nanotubes (BNNT)/boron nitride nanoplatelets (BNNP) foam (hybrid BNNT/BNNP foam), the method comprising:
preparing a slurry of slurry components, the slurry components comprising a freezing agent and a primary material of the hybrid BNNT/BNNP foam; and
freeze-drying the slurry at a temperature below −30° C. to give the hybrid BNNT/BNNP foam comprising the primary material,
the primary material comprising BNNT and BNNP,
the hybrid BNNT/BNNP foam being free-standing,
the hybrid BNNT/BNNP foam comprising a lamellar microstructure,
the preparing of the slurry comprising vortex mixing and sonication of the slurry components,
the freeze-drying comprising freezing the slurry and sublimation of at least a part of the slurry,
the freezing agent being deionized water, and
the hybrid BNNT/BNNP foam having a porosity of at least 95%.
