Abstract
Disclosed is a process for forming a CO2 capture element comprises providing a mixture of a monomer or monomer blend or a polymer binder, a miscible liquid carrier for the binder and a CO2 sorbent or getter in particle form, forming the mixture into a wet film or membrane, evaporating the liquid carrier to form a film or membrane, and treating the wet film or membrane to form pores in the body of the film or membrane. Also disclosed is a process of forming a CO2 capture element which comprises the steps of applying a mixture including a sorbent material and a polymer to an underlying material; polymerizing the mixture in place on the material; and aminating the polymer-coated material.
