Abstract: Porous three-dimensional networks of polyimide and porous three-dimensional networks of carbon and methods of their manufacture are described. For example, polyimide aerogels are prepared by mixing a dianhydride and a diisocyanate in a solvent comprising a pyrrolidone and acetonitrile at room temperature to form a sol-gel material and supercritically drying the sol-gel material to form the polyimide aerogel. Porous three-dimensional polyimide networks, such as polyimide aerogels, may also exhibit a fibrous morphology. Having a porous three-dimensional polyimide network undergo an additional step of pyrolysis may result in the three dimensional network being converted to a purely carbon skeleton, yielding a porous three-dimensional carbon network. The carbon network, having been derived from a fibrous polyimide network, may also exhibit a fibrous morphology.

Abstract: Polymeric aerogels, articles made from the polymeric aerogels and methods of making the polymeric aerogels are provided. The aerogels are made e.g. from crosslinkable monomers such as isocyanate monomers or phenolic monomers and a filler comprising crosslinkable hydroxyl groups. The filler may be natural (e.g. wood flour) or synthetic. The aerogels and products made therefrom exhibit low thermal conductivity and are mechanically strong. Due to their physical properties, these materials are used as e.g. building envelope components, such as walls, roofs and frames, to improve the thermal performance thereof, and may be used in a variety of other applications such as sound and insulation barriers in mechanical equipment, cryogenic containers, etc.

Abstract: Manufacturing a low-K dielectric organic/inorganic aerogel composite material and its application are provided. The manufacturing method comprises: (1) mixing; (2) hydrolysis; (3) condensation; (4) aging; (5) drying; (6) impregnating polymer solution; (7) phase separation and drying; and (8) cross-linking and curing. The manufacturing method can produce a low-K dielectric organic/inorganic aerogel composite material having a high strength. The low-K dielectric aerogel is in a porous structure, and its porosity is higher than 70% and its density is from 0.12 g/cm3 to 0.45 g/cm3. The dielectric property of the low-K dielectric aerogel decreases along with an increase of its porosity, wherein a dielectric constant thereof is from 1.28 to 1.89, and a dielectric loss thereof is from 0.052 to 0.023. The low-k dielectric aerogel can be used for a dielectric layer in a high-frequency circuit, an insulation layer in a semiconductor device or a microwave circuit in a communication integrated circuit.

Abstract: Porous three-dimensional networks of polyurea and porous three-dimensional networks of carbon and methods of their manufacture are described. In an example, polyurea aerogels are prepared by mixing an triisocyanate with water and a triethylamine to form a sol-gel material and supercritically drying the sol-gel material to form the polyurea aerogel. Subjecting the polyurea aerogel to a step of pyrolysis may result in a three dimensional network having a carbon skeleton, yielding a carbon aerogel. The density and morphology of polyurea aerogels can be controlled by varying the amount of isocyanate monomer in the initial reaction mixture. A lower density in the aerogel gives rise to a fibrous morphology, whereas a greater density in the aerogel results in a particulate morphology. Polyurea aerogels described herein may also exhibit a reduced flammability.
