Abstract: A primary amine polymer aerogel comprising greater than 5 wt. % of primary amine monomers covalently bound to cross-linking monomers, wherein the primary amine monomers are selected from vinyl amine. A secondary amine polymer aerogel comprising secondary amine monomers covalently bound to cross-linking monomers, the secondary amine monomers being a result of substituting a hydrogen atom from a primary amine polymer aerogel, the primary amine polymer aerogel comprising vinyl amine monomers covalently bound to the cross-linking monomers. A tertiary amine polymer aerogel comprising tertiary amine monomers covalently bound to cross-linking monomers, the tertiary amine monomers being a result of substituting hydrogen atoms from a primary amine polymer aerogel, the primary amine polymer aerogel comprising vinyl amine monomers covalently bound to the cross-linking monomers.

Abstract: 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.
