Abstract
Foams and methods of fabricating and using the same are provided. The foams can be three-dimensional (3D), free-standing, and/or rigid and can be used as, for example, nanofiller networks. The shape and size of the foam pore interconnected network can be tailorable/tailored. The foams can be, for example, hybrid one-dimensional (1D)/two-dimensional (2D) foams of 1D and 2D materials (e.g., hybrid boron nitride nanotube (BNNT)/boron nitride nanoplatelet (BNNP) foams). A freeze-drying-based method can be used to fabricate bulk porous foam, which can be used for, e.g., nanofiller for polymer nanocomposites.
