摘要： A polymer aerogel monolith comprising a polymer aerogel having a nitrogen content of greater than seven weight percent impregnated into a mesh. A method of manufacturing an amine-containing polymer aerogel monolith, includes combining a vinyl-containing cross-linking monomer, a vinyl-containing functional monomer, an organic solvent, and a radical initiator into a liquid mixture, applying the liquid mixture to a mesh fabric to produce a monomer-impregnated mesh, heating the monomer-impregnated mesh to produce a polymer aerogel monolith, washing the polymer aerogel monolith with acid to produce an ammonium-containing polymer aerogel monolith, and applying a base to neutralize the ammonium-containing polymer aerogel monolith to produce an amine-containing polymer aerogel monolith. A direct air capture module has one or more amine-containing polymer aerogel monoliths, one or more air flow channels positioned to pass air through the monolith A monolith comprising a poly(alkylamine-co-divinylbenzene) impregnated mesh.
