Background:

• Effective carbon dioxide (CO2) separation technology is crucial for environmental remediation.
• Mixed matrix membranes (MMMs), integrating polymers with nanofillers, are a key area in CO2 separation.
• MXenes, a novel class of 2D materials, show promise as functional nanofillers in MMMs.

Purpose of the Study:

• Analysis of structural properties, synthesis methods, and interfacial dynamics.
• Evaluation of CO2 transport mechanisms and membrane performance.

Main Results:

• MXenes' tunable layered structure and surface functional groups enhance membrane properties.
• MXenes improve polymer-filler compatibility, reduce agglomeration, and optimize morphology.
• MXene-based MMMs demonstrate potential for efficient CO2 separation.

Conclusions:

• MXene-based MMMs represent a frontier in CO2 separation technology.
• Addressing limitations like defects, aging, and scalability is key for innovation.
• Prospects are bright for developing sustainable, high-performance, and industrially viable membranes.
