Membrane fabrication methods, mechanisms, and modification of membranes for CO2 separation are discussed. Various types of membrane materials with high CO2 separation performance are summarized. Rapid prototyping can achieve precise control of the thickness of membranes and freely design the spatial structure of membranes, which provides a new development direction for material application and process combination. Hence, a critical comparison of membrane fabrication using different methods can provide a comprehensive overview on the potential of the rapid prototyping technology in membrane fabrication. This is important to demonstrate the prospects of the membrane technology development for CO2 separation.

“…Therefore, an energy-saving and efficient method to capture CO 2 from the flue gas and natural gas is urgently needed to curtail CO 2 emissions. − Amine-based solvents are a mature technology for CO 2 capture in traditional separation methods, but it suffers from significant drawbacks, such as high energy costs and potential environmental risks. Compared with the traditional amine-based solvent absorption separation method, membrane separation possessing the low-cost, no phase transition, and environmentally friendly characteristics is extensively adopted to remove CO 2 from gas mixtures. − During the membrane process, the performance of CO 2 separation membranes is usually evaluated by permeance and selectivity. As for the gas separation membrane, maintaining appropriate selectivity while improving permeance has been considered an important consideration for its practical applications. , However, traditional polymer membrane materials face a trade-off between permeability (permeance) and selectivity, which limits the CO 2 separation efficiency through the membrane processes. , …”

Sustainable and energy-efficient molecular separation requires membranes with high permeability and selectivity. Among various membranes, the mixed matrix membranes (MMMs) prepared from two-dimensional MXene materials with well-defined nanochannels are expected to be used for the precise separation of molecules. However, the stacking of a large number of 2D MXene nanosheets creates gas mass transfer barriers, resulting in a significant reduction in gas permeability. To solve this issue, herein, a high-performance self-supporting Pebax/CMC@MXene MMM was prepared by a combination of 2D MXene nanosheets with branched carboxymethyl cellulose (CMC) for CO2 gas separation from natural gas and flue gas. Gas separation experimental results show that the as-prepared self-supporting Pebax/CMC@MXene MMMs can significantly improve gas permeance and selectivity. When the loading of MXene nanosheets in the CMC@MXene filler was fixed at 1.5 mg/mL, the CO2 permeance of Pebax/CMC@MXene MMMs was found to be 521 GPU, and the CO2/N2 selectivity was calculated to be 40.1. Meanwhile, the CO2 permeance was measured to be 444 GPU, and the CO2/CH4 selectivity was calculated to be 40.4. In addition, the resulted as-prepared self-supporting Pebax/CMC@MXene MMM possesses excellent thermal stability and long-term durability; after a 60 h test, its separation performance has no obvious change. The work provides a novel strategy to construct MMMs with less mass transfer barrier for highly efficient capture of CO2 from natural gas and flue gas.
