Ultramicroporous polyimides with hierarchical morphology for carbon dioxide separation
Marion Breunig, Melanie Dorner, Jürgen Senker
Abstract
Two polyimides with hierarchical porosity were prepared by adjusting the composition of an <italic>m</italic>-cresol/toluene solvent mixture. The large proportion of ultramicropores led to exceptional selectivity for separating CO<sub>2</sub> from CH<sub>4</sub>.
