Three related UV-initiated, free-radical photopolymerized systems containing PEG were demonstrated as potential synthetic approaches to fabricate new membranes for various CO2 separation processes. Elastomeric thiol-ene PEG-based networks with varying crosslink density, thiol-modified PEG diacrylate networks, and PEG/PDMS acrylate networks were explored. By employing each of these systems, polymer networks with controlled molecular-level topologies were formed rapidly and without the use of solvents. This work demonstrates not only the energy efficiency and ease of UV curing as a membrane fabrication approach but also the fundamental structure-property relationships and promising membrane performance results that can be obtained.
