Title: Impact of tuning CO ₂-philicity in polydimethylsiloxane-based membranes for carbon dioxide separation

Abstract

Amidoxime-functionalized polydimethylsiloxane (AO-PDMSPNB) membranes with various amidoxime compositions were synthesized via ring-opening metathesis polymerization followed by post-polymerization modification. Compared to other previously reported PDMS-based membranes, the amidoxime-functionalized membranes show enhanced CO ₂ permeability and CO ₂/N ₂ selectivity. The overall gas separation performance (CO ₂ permeability 6800 Barrer; CO ₂/N ₂ selectivity 19) of the highest performing membrane exceeds the Robeson upper bound line, and the excellent permeability of the copolymer itself provides great potential for real world applications where huge volumes of gases are separated. This study details how tuning the CO ₂-philicity within rubbery polymer matrices influences gas transport properties. Key parameters for tuning gas transport properties are discussed, and the experimental results show good consistency with theoretical calculations. Finally, this study provides a roadmap to enhancing gas separation performance in rubbery polymers by tuning gas solubility selectivity.

Effect of cross-link density on carbon dioxide separation in polydimethylsiloxane-norbornene membranes

Journal Article Hong, Tao ; Niu, Zhenbin ; Hu, Xunxiang ; ... - ChemSusChem

Here, the development of high-performance materials for carbon dioxide separation and capture will significantly contribute to a solution for climate change. Herein, (bicycloheptenyl)ethylterminated polydimethylsiloxane (PDMSPNB) membranes with varied cross-link densities were synthesized via ring-opening metathesis polymerization. The developed polymer membranes show higher permeability and better selectivity than those of conventional cross-linked PDMS membrane. The achieved performance (CO ₂ permeability ≈ 6800 Barrer; CO ₂/N ₂ selectivity ≈ 14) is very promising for practical applications. The key to achieving this high performance is the use of an in situ cross-linking method for difunctional PDMS macromonomers, which provides lightly cross-linked membranes. Bymore »« less

Highly Permeable Oligo(ethylene oxide)- co-poly(dimethylsiloxane) Membranes for Carbon Dioxide Separation

Journal Article Hong, Tao ; Lai, Sophia C. ; Mahurin, Shannon Mark ; ... - Advanced Sustainable Systems

Here, a series of cross–linked, freestanding oligo(ethylene oxide)– co–(polydimethylsiloxane–norbornene) membranes with varied composition is synthesized via in situ ring–opening metathesis polymerization. These membranes show remarkably high CO ₂ permeabilities (3400 Barrer) and their separation performance approaches the Robeson upper bound. The excellent permeability of these copolymer membranes provides great potential for real–world applications where enormous volumes of gases must be separated. The gas transport properties of these films are found to be directly proportional to oligo(ethylene oxide) content incorporation, which stems from the increased solubility selectivity change within the copolymer matrix. This work provides a systematic study of how gasmore »« less

The CO ₂ permeability and mixed gas CO ₂/H ₂ selectivity of membranes composed of CO ₂-philic polymers

Journal Article Barillas, Mary Katharine ; Enick, Robert M. ; O’Brien, Michael ; ... - Journal of Membrane Science

The objective of this work was to design polymeric membranes that have very high CO ₂ permeability and high mixed gas selectivity toward CO ₂ rather than hydrogen. Therefore the membranes were based on "CO ₂-philic" polymers that exhibit thermodynamically favorable Lewis acid:Lewis base and hydrogen bonding interactions with CO ₂. CO ₂-philic polymers that are solid at ambient temperature include polyfluoroacrylate (PFA); polyvinyl acetate (PVAc); and amorphous polylactic acid (PLA). Literature CO ₂ permeability values for PVAc and PLA are disappointingly low. The cast PFA membranes from this study had low permeabilities (45 barrers at 25º C) and verymore »« less

Gas separation mechanism of CO ₂ selective amidoxime-poly(1-trimethylsilyl-1-propyne) membranes

Journal Article Feng, Hongbo ; Hong, Tao ; Mahurin, Shannon Mark ; ... - Polymer Chemistry

Polymeric membranes for CO ₂ separation have drawn significant attention in academia and industry. We prepared amidoxime-functionalized poly(1-trimethylsilyl-1-propyne) (AO-PTMSP) membranes through hydrosilylation and post-polymerization modification. Compared to neat PTMSP membranes, the AO-PTMSP membranes showed significant enhancements in CO ₂/N ₂ gas separation performance (CO ₂ permeability ~6000 Barrer; CO ₂/N ₂ selectivity 17). This systematic study provides clear guidelines on how to tune the CO ₂-philicity within PTMSP matrices and the effects on gas selectivity. Key parameters for elucidating the gas transport mechanism were discussed based on CO ₂ sorption measurements and fractional free volume estimates. The effect of themore »« less

Tailored CO ₂ -philic Gas Separation Membranes via One-Pot Thiol–ene Chemistry

Journal Article Hong, Tao ; Cao, Peng-Fei ; Zhao, Sheng ; ... - Macromolecules

Recently, thiol–ene chemistry attracts much attention in the construction of functional polymer materials due to its versatility and fast reaction kinetics, though only a few studies have been reported on its utilization in the fabrication of elastic polymer materials. Herein, a series of elastic, poly(dimethylsiloxane)–poly(ethylene glycol) methyl ether acrylate (PDMS–PEGMEA)-based co-polymer membranes are synthesized via a one-pot thiol–ene reaction. These membranes are highly stable and exhibit tunable thermal/mechanical properties by tailoring the cross-linker and side-chain functionality. When used for gas separation application, all grafted elastomer membranes show excellent gas permeability and selectivity, and the membrane with an optimal composition (PDMS–PEGMEAmore »« less
