Support-free adsorbents for CO 2 capture from air

Abstract

A resin includes a functionalized aminopolymer having amine sites for capturing carbon dioxide molecules, where each aminopolymer molecule has at least one functional group amenable to crosslinking, a porogen, and a crosslinking initiator. A product includes an aminopolymer material formed into a self-supporting structure, the aminopolymer material including crosslinked aminopolymers having amine sites for the capture of carbon dioxide molecules.
