Mixed-Matrix Membrane Hollow Fibers of Cu3(BTC)2 MOF and Polyimide for Gas Separation and Adsorption
Abstract
Metal−organic framework (MOF) crystals of Cu 3 (BTC) 2 with a high surface area (1396 m 2 ·g −1 ) were synthesized and mixed with polyimide (PI) to prepare mixed-matrix membranes (MMMs) for gas separations. The PI−Cu 3 (BTC) 2 blend was successfully spun into MMM hollow fiber by the dry/wet-spinning method. SEM images of the fiber cross sections revealed significant plastic deformation of the polymer matrix owing to the strong affinity between Cu 3 (BTC) 2 and PI. The H 2 permeance and the selectivity of H 2 with respect to other gases such as N 2, CO 2, O 2, and CH 4 both increased markedly with increased Cu 3 (BTC) 2 loading. At a loading of 6 wt % Cu 3 (BTC) 2, the permeance of H 2 increased by 45%, and the ideal selectivity increased by a factor of 2−3 compared to the corresponding values for pure PI.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
