摘要
Novel inorganic-organic hybrid membranes Fe@MWCNT/PPO or Fe@MWCNT-OH/SPPO (with a new type of CNTs characterized by increased iron content 5.80 wt%) were synthesized for CO<INF>2</INF> separation. The introduction of nanofillers into the polymer matrix has significantly improved the hybrid membrane's gas transport (D, P, S, and alpha<INF>CO<INF>2</INF>/N<INF>2</INF></INF>), magnetic, thermal, and mechanical parameters. It was found that magnetic casting has improved the alignment and dispersion of Fe@MWCNTs. At the same time, CNTs and polymer chemical modification enhanced interphase compatibility and the membrane's CO<INF>2</INF> separation efficiency. The thermo-oxidative stability and mechanical and magnetic parameters of composites were improved by increasing new CNTs loading. Cherazi's model turned out to be suitable for describing the CO<INF>2</INF> transport through analyzed hybrid membranes.
