Abstract: Functionalized materials that act as sorbent, as well as methods of making such materials and systems of using such materials, are provided. The disclosed processes, methods, and materials can be used for the separation of CO2 from fluid streams. In one aspect, the disclosed materials are synthesized by forming coated particles through the introduction of porous particles, such as silica, to a first reagent comprising a polymer. Then the functionalized material is formed as functionalized coated particles by the introduction of a second reagent comprising at least one adsorbing moiety to the surfaces of the coated particles. Formation of the functionalized material is in the presence of a chelating agent, antioxidant, and/or crosslinker. In some instances, formation of the functionalized material is further in the presence of a third reagent comprising an interaction moiety that is incorporated into the functionalized coated particles.

Abstract: Disclosed herein are methods, and compositions produced using the methods, including introducing porous substrate particles and a first reagent comprising a polymer to a solvent to provide a plurality of coated particles; and introducing a second reagent comprising a polymeric amine and a third reagent comprising a silane moiety and an amine moiety to the coated particles, thereby providing a plurality of functionalized, coated particles.

Abstract: Functionalized and crosslinked material, which may optionally be employed as a sorbent, as well as methods of making such materials and systems of using such materials are provided. The processes, methods, systems and materials herein can be used for the separation of carbon dioxide from fluid streams. In one aspect, a method of forming functionalized crosslinked particles comprises introducing at least a portion of a surface of each porous particle in at least a subset of a plurality of porous particles to a crosslinking agent and a first reagent comprising at least one adsorbing moiety. Examples of adsorbing moiety include silane-functionalized amines, amino-functionalized silanes (aminosilane), and polyamines. In some aspects the method further comprises introducing the porous particles to a second reagent comprising at least one interaction moiety such as a silane-functionalized amine, amino-functionalized silane (aminosilane), or polyamine.

Abstract: Aspects of the disclosure relate to envelopes for aerial vehicle. The aerial vehicle may include an envelope including a plurality of gores. The aerial vehicle may also include a seal arranged between a pair of the plurality of gores, the seal including six layers of envelope material heat-sealed together.
