“…[58,62,63] Besides, the solubility selectivity is influenced by more condensable gas molecules that have a higher critical temperature of CO 2 gas and preferred CO 2 permeation over CH 4 [57] as well as the condition of polymer-filler interface. [64] Meanwhile, the CO 2 /CH 4 diffusivity selectivity is impacted by the size of penetrating gas and free volume in the membrane. [64] Due to the smaller kinetic diameter of CO 2 gas (3.3 Å) compared with CH 4 gas (3.8 Å), induced higher CO 2 permeation was observed in comparison with F I G U R E 4 CO 2 permeability against (1 + bp) À1 of M0, M1, and M2 membranes CH 4 gas.…”

“…PEO-polyurethane was used for biomedical and gas separation applications due to its good mechanical properties and structural interchangeability. Nebipasagil et al [22] synthesized copolymers of poly(arylene ether sulfone) and poly(ethylene oxide) (PEO)based segmented polyurethanes. The CO 2 /CH 4 , CO 2 /N 2 selectivity increased with increasing PEO content in polyurethane.…”

Amphiphilic Poly(dimethylsiloxane-ethylene-propylene oxide)-polyisocyanurate Cross-Linked Block Copolymers in a Membrane Gas Separation

Amphiphilic poly(dimethylsiloxane-ethylene-propylene oxide)-polyisocyanurate cross-linked block copolymers based on triblock copolymers of propylene and ethylene oxides with terminal potassium-alcoholate groups (PPEG), octamethylcyclotetrasiloxane (D4) and 2,4-toluene diisocyanate (TDI) were synthesized and investigated. In the first stage of the polymerization process, a multiblock copolymer (MBC) was previously synthesized by polyaddition of D4 to PPEG. The usage of the amphiphilic branched silica derivatives associated with oligomeric medium (ASiP) leads to the structuring of block copolymers via the transetherification reaction of the terminal silanol groups of MBC with ASiP. The molar ratio of PPEG, D4, and TDI, where the polymer chains are packed in the “core-shell” supramolecular structure with microphase separation of the polyoxyethylene, polyoxypropylene and polydimethylsiloxane segments as the shell, was established. Polyisocyanurates build the “core” of the described macromolecular structure. The obtained polymers were studied as membrane materials for the separation of gas mixtures CO2/CH4 and CO2/N2. It was found that obtained polymers are promising as highly selective and productive membrane materials for the separation of gas mixtures containing CO2, CH4 and N2.
