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.

WATER PURIFICATION METHOD WITH NANOCOMPOSITE SORBENT

A method for producing a nanocomposite sorbent comprising carbon nanotube-grafted acrylic acid/acrylamide copolymer which involves copolymerization of acrylic acid and acrylamide in the presence of an aqueous dispersion of carbon nanotubes. The method yields a nanocomposite sorbent material having a reversible adsorption capacity phenol of 5 to 2500 μg of phenol per mg of nanocomposite sorbent. Also disclosed is a method for removing organic pollutants from water using the nanocomposite sorbent.
