Separation performance of asymmetric membranes based on PEGDa/PEI semi-interpenetrating polymer network in pure and binary gas mixtures of CO2, N2 and CH4

Role of critical concentration of PEI in NMP solutions on gas permeation characteristics of PEI gas separation membranes

“…PDMS is the most commonly used rubbery membrane material for heavy hydrocarbons separation processes [15,16]. Due to structural properties such as unique flexibility of the siloxane backbone, low intermolecular forces between the methyl groups and high bonding energy of the siloxane bond, it can be used as a coating layer for preparation of the defect free membrane by phase inversion method [17][18][19].…”

Polymeric Membrane for CO2/CH4 Separation

“…Interestingly, the carbon nanosheets are produced from biomass-derived of monkeypod tree leaves. Based on the final analysis, the gas separation had a selectivity value of 42.73 for CO2/CH4, compared with bare PEI membrane at 23.30 [44]. [40].…”

Pore Structure Controllability and CO2 Permeation Properties of Silica-Derived Membranes with a Dual-Network Structure

“…Interpenetrating network (IPN)-derived materials, with the dispersion of two different materials in the molecule-level, are believed to combine the advantages of each network and overcome the shortcomings of MMMs. − Theoretically, the materials in IPNs should have strong interactions or compatibility via covalent bonds, hydrogen bonds, electrostatic forces, dipole–dipole forces, and Van der Waals’ forces. Some researchers have synthesized CO 2 separation membranes with organic–organic IPNs and/or semi-IPN structures. − As far as we could ascertain, however, organosilica/polymer-based IPN membranes for CO 2 separation have rarely been reported.…”
