SEGMENTED FLEXIBLE GEL COMPOSITES AND RIGID PANELS MANUFACTURED THEREFROM
The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.
Hydrophobic aerogel materials
The present disclosure provides an aerogel composition which is durable and easy to handle, which has favorable performance in aqueous environments, and which also has favorable combustion and self-heating properties. Also provided is a method of preparing an aerogel composition which is durable and easy to handle, which has favorable performance in aqueous environments, and which has favorable combustion and self-heating properties. Further provided is a method of improving the hydrophobicity, the liquid water uptake, the heat of combustion, or the onset of thermal decomposition temperature of an aerogel composition.
Methods of Making Permeable Aerogels
Methods of making permeable aerogels (100) can include providing a sol mixture (110) comprising an organic scaffold, an inorganic aerogel precursor, and a first solvent. The organic scaffold can be insoluble in the first solvent. The sol mixture can react to form a gel (120) such that an interconnected channel network is formed which is at least partially defined by the organic scaffold. The first solvent in the gel can be exchanged (130) with a second solvent. The second solvent can dissolve the organic scaffold to expose the interconnected channel network. The gel can be dried (140) to form the permeable aerogel.
HIGH-TEMPERATURE POLYMER AEROGEL COMPOSITES
High-temperature polymer aerogel composites, associated materials, associated methods of manufacture, and applications of polymer aerogel composites including engine covers comprising aerogel materials are generally described.
Method of preparing carbon aerogel precursor, carbon aerogel precursor prepared thereby, and carbon aerogel
The present invention relates to a carbon aerogel precursor, a preparation method thereof and a carbon aerogel prepared thereby and, more particularly, to a carbon aerogel precursor which can be converted into a carbon aerogel that exhibits excellent specific surface area and physical properties by using a binder that has a low carbonization ratio and is capable of performing phase conversion while using a carbon material having physical properties such as diameter, length and the like that are not adjusted, a preparation method thereof, and a carbon aerogel prepared thereby.
Systems and methods for aerogel preparation via vacuum-assisted solvent exchange and ambient pressure drying
Systems and methods are provided for aerogel processing and production via vacuum-assisted solvent exchange and ambient pressure drying. In one example, a method includes injecting a solvent at each of a top surface and a base of a saturated aerogel and applying a vacuum-assisted pressure differential across the saturated aerogel to achieve solvent exchange. In some examples, following solvent exchange, the aerogel may be dried in ambient pressure and integrated in a vehicle component. In this way, a rate of solvent exchange may be increased, concomitantly increasing aerogel production efficiency. Further, in some examples, the aerogel may be protected from premature drying during solvent exchange.
Internally reinforced aerogel and uses thereof
Internally reinforced aerogels, articles of manufacture and uses thereof are described. An internally reinforced aerogel includes an aerogel having a support at least partially penetrating the aerogel and having the aerogel penetrating the porous structure of the support.
Organic polymer aerogels comprising microstructures
Organic polymer aerogels, articles of manufacture, and uses thereof are described. The aerogels include an organic polymer matrix and microstructures dispersed within the aerogels, which provides for superior thermal conductivity and mechanical properties.
TUNABLE, RAPID UPTAKE, AMINOPOLYMER AEROGEL SORBENT FOR DIRECT AIR CAPTURE OF CO2
A porous polymer aerogel, wherein the aerogel has greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone. A method of fabrication of a porous polymer aerogel amine material, includes preparing a solution comprising at least a solvent, amine monomers having protected amino groups, one or more crosslinkers, one or more radical initiators, and a nitroxide mediator, removing oxygen from the solution, heating the solution to promote polymerization and to produce a polymerized material, performing solvent exchange with the polymerized material, causing a deprotection reaction in the polymerized material to remove groups protecting the amino groups, soaking and rinsing the material to remove excess reagents and any byproducts of the deprotection reaction, and drying the material to produce the amine sorbent. A system to separate CO2 from other gases, comprising a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone.
