Abstract
A method of separating a gas mixture, including contacting the gas mixture with a membrane and passing a portion of the gas mixture through the membrane. The portion of the gas mixture that passes through the membrane includes carbon dioxide. The membrane includes a poly(ether-block-amide) (PEBAX) and a covalent organic framework (COF). The COF is an optionally substituted COF-316 and the COF is dispersed in a matrix of the PEBAX to form the membrane. The membrane includes 0.1-5 wt. % of the COF relative to a total weight of the membrane.
