Major Contributions

1.Comprehensive Review of Membrane Materials
We conducted an in-depth review of five major types of membrane materials—dense polymers, microporous polymers, framework materials, two-dimensional (2D) materials, and others. We analyzed their intrinsic properties and design principles, highlighting their potential for achieving high permeability and selectivity in various CO₂ separation applications.

2.Bridging the Gap Between Material Development and Practical Applications
We identified critical challenges in transitioning advanced materials into industrially viable asymmetric membranes. These challenges include material processability, mechanical stability, scalability, and the ability to meet commercial requirements for carbon capture technologies.

3.Summarization of Asymmetric Membrane Fabrication Techniques
We summarized state-of-the-art fabrication methods for asymmetric membranes, focusing on how these techniques optimize the combination of mechanical support layers with thin selective layers. This work provides practical insights into improving membrane performance for real-world CO₂ capture.

4.Future Perspectives on Membrane Development
We proposed forward-looking strategies to advance membrane technology, including the development of innovative materials, improved fabrication techniques, and hybrid system integration. These perspectives aim to address current limitations and accelerate the commercialization of high-performance membranes.
