Membranes for co2 capture

Abstract

Provided are articles and membranes, which may be functional membranes, that address the limitations of membranes known in the art. The membranes can be formed from porous substrates, carbon nanotubes, CO2-philic components, and quantum dots and provide much higher selectivity than other membranes previously reported, which is at least an order of magnitude higher than commercial membranes, and thus can enrich CO2 from 4% to 97% in one step. Also, the membranes of the present disclosure are stable under high vacuum operation and can maintain high CO2 separation performance for at least 100 hours. For example, highly permeable membranes or highly selective membranes can be obtained by manipulating nano-confined frameworks and active CO2-philic components.
