摘要： A membrane for use in gas separation may contain a polymer having at least one of either polyimide poly[(naphthalene-1,5-diamine)-alt-(biphenyl-3,3′:4,4′-tetracarboxylic dianhydride)] or poly[isophoronediamine-alt-(biphenyl-3,3′,4,4′-tetracarboxylic anhydride)]. These polyimides were predicted to exhibit above-threshold performance for separating multiple gas pairs for use in industrial applications, such as air separation (O2/N2) and hydrogen separations (H2/CH4, H2/N2), based on a novel graph neural network machine learning model. Performance may be predicted by analyzing polymer properties and structure and comparing against labeled or known performance data for other known polymers. The performance of the polymers for use in gas membranes may then be experimentally verified.
