A Novel Imide-Bridged Polysiloxane Membrane Was Prepared via One-Pot Hydrosilylation Reaction for O(2)/N(2) Separation
[Image: see text] The synthesis of poly(methyhydrosiloxane) (PMHS) and N,N′-bis(3-allyl)pyromellitic diimide was optimized for O(2)/N(2) separation. The membrane exhibits excellent mechanical and thermal properties and shows an O(2)/N(2) selectivity of up to 4.44 with an O(2) permeability of 31.0 Ba...

| description | [Image: see text] The synthesis of poly(methyhydrosiloxane) (PMHS) and N,N′-bis(3-allyl)pyromellitic diimide was optimized for O(2)/N(2) separation. The membrane exhibits excellent mechanical and thermal properties and shows an O(2)/N(2) selectivity of up to 4.44 with an O(2) permeability of 31.0 Barrer; compared with polydimethylsiloxane (PDMS) and pure polyimide (PI) membranes, the separation selectivity shows a 107% increase for PDMS, and the permeation shows a 660% increase for pure PI. The obtained results were well above the ones reported on the literature for similar conditions opening the door for the preparation of a stable polysiloxane (PMHS-I) gas separation membrane with extraordinary O(2)/N(2) separation performance. |
