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.

Foams of nanomaterials and fabrication methods thereof

Foams and methods of fabricating and using the same are provided. The foams can be free-standing and 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, transition metal dichalcogenide (TMD) foams with a layered structure (e.g., tungsten sulfide (WS) foams). A freeze-drying-based method can be used to fabricate bulk porous foam, which can be used for, e.g., polymer nanocomposites. A vacuum-assisted infiltration procedure can be used to fabricate a foam-polymer nanocomposite.

Ultra-high temperature carbide (UHTC) foams and methods of fabricating and using the same are provided. The UHTC foams are produced in a three-step process, including UHTC slurry preparation, freeze-drying, and spark plasma sintering (SPS). The fabrication methods allow for the production of any kind of single- or multi-component UHTC foam, while also providing flexibility in the shape and size of the UHTC foams to produce near-net-shape components.

The subject invention provides compositions, systems, and methods for additive manufacturing (AM), including three dimensional printing (3DP) using Digital Light Processing (DLP), of Lunar regolith and Lunar regolith simulants including Greenland Anorthosite Lunar Regolith (GALR) with a photocurable thermosetting polymer. Certain embodiments provide a high solid content of regolith, for example, about 60 wt. % GALR; together with a lower content of additives, for example, about 40 wt. % of a photocurable thermosetting polymer. Embodiments of the provided recipe and processing method can produce parts with low shrinkage, high strength, and favorable thermal properties. Parts have been produced with less than about 6% shrinkage in multiple directions of measurement.

A graphene foam ceramic composite (GrF-CC) comprises an open cell graphene foam (GrF) surrounded by and infiltrated with a sintered low temperature co-fired ceramic (LTCC) matrix. The GrF-CC can be prepared by infiltrating an open cell GrF with an LTCC slurry, removing the solvent from the slurry with solidification to a ceramic-GrF green body, and sintering the ceramic-GrF green body to form the GrF-CC. Sintering by spark plasma sintering (SPS) allows an LTCC GrF-CC that has a density of at least 90%.

Method to produce graphene foam reinforced low temperature co-fired ceramic (LTCC) composites

Shape memory polymer (SMP) epoxies and composites, and methods of manufacturing the same, are provided. A three-dimensional (3D) printing technique can be used to fabricate a pure thermoset SMP epoxy. A cryogenic sprayer assisted extrusion type 3D printing method can be used to print SMP epoxies and composites of an SMP epoxy and a nanomaterial additive, such as graphene nanoplatelets (GNP).
