In this study, precursor molecules based on PEG/PPG and polydimethylsiloxane (PDMS), both widely used rubbery polymers, were copolymerized with bulky adamantane into copolymer membranes. Ring-opening metathesis polymerization (ROMP) was employed during the polymerization process to create a structure with both ends crosslinked. The precursor molecules and corresponding polymer membranes were characterized using various analytical methods. The polymer membranes were fabricated using different compositions of PDMS and adamantane, to determine how the network structure affected their gas separation performance. PEG/PPG, in which CO2 is highly soluble, was copolymerized with PDMS, which has high permeability, and adamantane, which controlled the crosslinking density with a rigid and bulky structure. It was confirmed that the resulting crosslinked polymer membranes exhibited high solubility and diffusivity for CO2. Further, their crosslinked structure using ROMP technique made it possible to form good films. The membranes fabricated in the present study exhibited excellent performance, i.e., CO2 permeability of up to 514.5 Barrer and CO2/N2 selectivity of 50.9.

“…[26] While not much work has been reported on 3D-printed gas separation membranes, AM proves to be a potential means of fabricating such materials due to its capability and flexibility to produce geometrically complex and multilayered structures, with control on macroscopic geometry and porosity, [27] at faster speeds and relatively low-costs. [28][29][30] Exploiting the perks of 3D printing process for the realization of permeable and selective gas separation membrane materials could pave the way towards a high-performing, economical, and sustainable CO 2 capture method. This work explores several useful membrane materials used for CO 2 capture and discusses the separation mechanisms involved and fabrication via 3D printing.…”

The potential of additively manufactured membranes for selective separation and capture of CO2

et al. 2021

Additive manufacturing (or 3D printing) is an evolving technology that shows great potential as a sustainable method for fabricating gas separation membranes for carbon capture applications. Compared to other gas separation techniques or membranes fabricated by conventional formative methods, the use of 3D-printed membranes is more advantageous because of their simplicity, higher energy efficiency, practicality, flexible and tailorable designs, and high separation efficiency. Although polymeric, cementitious, and gel-based materials have been exploited for the development and fabrication of robust and highly efficient CO 2 -capturing membranes, these materials require further innovation to become fit and suitable as feedstock for 3D printers. In this work, we review several and potential membrane materials used for capturing CO 2 and discuss their corresponding separation mechanisms and fabrication via 3D printing. We also summarize the challenges and limitations in using 3D-printed membranes and provide perspectives towards high-performance membrane fabrication and future industrial applications.

“…Polyimide is one of the most widely used glassy polymers, and it provides excellent thermal stability, chemical durability, and mechanical strength [8,9,[12][13][14][15]. For that reason, the material has been widely used in a variety of applications, including batteries, shape memory devices, sensors, wearable devices, and gas-separation membranes [13].…”

A series of CO2-selective polyimides (CE-PDMS-PI-x) was synthesized by copolymerizing crown ether diamine (trans-diamino-DB18C6) and PDMS-diamine with 4,4′-(hexafluoroisopropylidene) di-phthalic anhydride (6FDA) through the polycondensation reaction. The structural characteristics of the copolymers and corresponding membranes were characterized by nuclear magnetic resonance (NMR), infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and gel permeation chromatography (GPC). The effect of PDMS loading on the CE-PDMS-PI-x copolymers was further analyzed and a very good structure–property relationship was found. A well-distributed soft PDMS unit played a key role in the membrane’s morphology, in which improved CO2-separation performance was observed at a low PDMS content (5 wt %). In contrast, the fine-grained phase separation adversely affected the separation behavior at a certain level of PDMS loading, and the PDMS was found to provide a flexible gas-diffusion path, affecting only the permeability without changing the selective gas-separation performance for the copolymers with a PDMS content of 20% or above.
