Description
In response to the urgent need for efficient carbon dioxide (CO₂) capture techniques from industrial processes, membrane-based gas separation has emerged as a promising approach due to its cost-effectiveness, safety, environmental benefits, and energy efficiency. Among the various materials employed, polymeric membranes have attracted considerable attention because of their suitability for large-scale deployment. However, despite the successful commercialization of polymeric membranes, they suffer from an inherent permeability–selectivity trade-off.
A promising strategy to overcome this limitation involves the use of mixed matrix membranes (MMMs), which integrate porous fillers within a polymer matrix. MMMs combine the processability of polymers with the superior selectivity and permeability of porous materials. The development of efficient MMMs depends on several critical factors, including membrane morphology, polymer type, filler particle characteristics, particle dispersion, plasticization, and physical aging. Performance enhancements can also be achieved through modifications such as optimizing filler size, shape, and loading, adding additives, and implementing surface modifications on fillers.
In this presentation, I will share our recent findings on how geometrically optimized fillers can significantly improve the efficiency of MMMs designed for gas separation. In the first part of the presentation, I will discuss how Platonic-shaped fillers influence the design criteria for optimal membranes using a computational approach. The evaluation considers both single- and binary-gas transport to assess permeability and selectivity. The second part of the presentation focuses on the design of MMMs by identifying the sources of incompatibility that prevent achieving ideal membrane performance and on developing effective strategies to overcome these challenges.
