Abstract

This paper introduces a novel molecular soldering strategy using multifunctional polyphenols to enhance the performance of mixed-matrix membranes (MMMs) for carbon capture. By improving polymer-MOF interfacial compatibility and creating a hollow MOF structure, the strategy overcomes the permeability-selectivity trade-off, resulting in superior CO2 separation performance compared to conventional MMMs. The method is validated using various polymers, suggesting its broad applicability.
