Abstract:
Enclosures of several type useful in transportation or thermally sensitive materials comprising a fiber reinforced aerogel material is described. Enclosures may take several forms and the aerogel material may be encapsulated with polymeric materials. Various methods of manufacturing such enclosures are also described.
Abstract:
Embodiments of the present invention describe an insulation system comprising: a primary shell; a secondary shell positioned to cover at least a portion of the primary shell; a cryogenic fluid contained by the primary shell and at least one load-bearing primary insulation component disposed between the secondary shell and the primary shell. Optionally an intermediary shell is placed between the primary shell and the secondary shell along with a secondary insulation component resulting in a shell/ insulation /shell / insulation/shell arrangement. In either arrangement, the primary, secondary or both insulation components comprise a material with a nanoporous aerogel optionally reinforced with a fibrous element.
Abstract:
The present invention relates to cross-linked polyolefin aerogels in simple and fiber-reinforced composite form. Of particular interest are polybutadiene aerogels. Especially aerogels derived from polybutadienes functionalized with anhydrides, amines, hydroxyls, thiols, epoxies, isocyanates or combinations thereof.
Abstract:
The present disclosure describes aerogel composites comprising organic-inorganic hybrid aerogel particulates and binders, in particular systems with aerogel and binders covalently bonded along with methods for preparing the same. Said composites can be formed into articles having complex geometries.
Abstract:
Aerogel-based thermal management systems and methods for vehicles incorporate aerogel materials to provide insulation and heat shielding. Various components of a vehicle must be protected from high temperature, and conventional insulation undesirably adds weight and mass to the vehicle. Aerogel materials can be used for heat insulation and heat shielding while consuming minimal space and weight in the vehicle. The aerogel materials can be provided in monolithic or fiber-reinforced composite form, and can be enclosed in an encapsulating material such as a polymer, elastomer, or metal. The aerogel material is then attached on or near an automobile component.
Abstract:
The invention provides reinforced aerogel monoliths as well as fiber reinforced composites thereof for a variety of uses. Compositions and methods of preparing the monoliths and composites are also provided.
Abstract:
Drugs in the form of very fine highly porous aerogel particles are delivered to a patient via inhalation. The aerogel particles are either an aerogelized form of a pharmaceutical or deposited upon aerogel particles produced from a non-inorganic oxide carrier matrix material, e.g. a sugar or carbohydrate. The aerogel particles are readily dissolvable by the pulmonary surfactant present in the lungs of a mammals.
Abstract:
A method is described for enhancing mass and heat transport of fluids in a fine pore structure through an appropriate modulation of the fluid pressure. For example, in an air drying process for a porous material that contains liquid, the air pressure is modulated throughout the volume of the drying chamber. Alternatively, the fluid pressure is modulated in a process stream. As an example, this method can be used for rapid drying of any open porous substances ranging from small pored materials such as aerogels and xerogels, to larger pored substances or articles such as industrial articles, agricultural articles (e.g., densely stacked vegetables, coffee beans, hops and other grains), paper-based products, thin, films, pharmaceuticals, cloth, and clothing.
Abstract:
Aerogel composite materials having a lofty fibrous batting reinforcement preferably in combination with one or both of individual short randomly oriented microfibers and conductive layers exhibit improved performance in one or all of flexibility, drape, durability, resistance to sintering, x-y thermal conductivity, x-y electrical conductivity, RFI-EMI attenuation, and/or burn-through resistance.
Abstract:
The present disclosure is directed to methods of forming polyimide gels. The methods generally include forming a polyamic acid and dehydrating the polyamic acid with a dehydrating agent in the presence of water. The resulting polyimide gels may be converted to polyimide or carbon xerogels or aerogels. The methods are advantageous in providing rapid or even instantaneous gelation, which may be particularly useful in formation of beads comprising the polyimide gels. Polyimide or carbon gel materials prepared according to the disclosed method are suitable for use in environments containing electrochemical reactions, for example as an electrode material within a lithium-ion battery.
