What is claimed is: 1. 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. 2. The primary amine polymer aerogel of claim 1 , wherein the cross-linking monomers are selected from divinylbenzene. 3. The primary amine polymer aerogel of claim 1 , wherein the cross-linking monomers are selected from the group consisting of: trimethylolpropane triacrylate, trimethylolpropane ethoxylate triacrylate, di(trimethylolpropane) tetraacrylate, dipentaerythritol penta-/hexa-acrylatetrimethacryl adamantane, dipentaerithritol, trimethylolpropane trimethacrylate, phenylene dimethacrylate, phenylene diacrylate, and 1,6-hexanediol diacrylate. 4. The primary amine polymer aerogel of claim 1 , wherein the primary amine polymer aerogel adsorbs greater than 1 millimole carbon dioxide per gram of primary amine polymer aerogel at temperatures greater than 0° C. and carbon dioxide concentrations less than 1000 parts per million. 5. The primary amine polymer aerogel of claim 1 , wherein the primary amine polymer aerogel adsorbs greater than 1 millimole carbon dioxide per gram of primary amine polymer aerogel at temperatures greater than 20° C. and carbon dioxide concentrations less than 500 parts per million. 6. The primary amine polymer aerogel of claim 1 , the primary amine polymer aerogel having a porosity greater than 10%. 7. The primary amine polymer aerogel of claim 1 , the primary amine polymer aerogel comprising greater than 10 wt. % of primary amine monomers. 8. The primary amine polymer aerogel of claim 1 , the primary amine polymer aerogel further comprising carbon dioxide adsorbed to the vinyl amine monomers.
