ABSTRACT The growing interest in utilizing mixed matrix membranes (MMMs) based on polyurethane (PU) for gas separation applications has prompted extensive research efforts in both industry and academia. Although incorporating different fillers has shown promising enhancements in the efficiency and durability of PU membranes, several challenges related to optimal filler integration need to be addressed. This study aims to overcome these challenges by conducting a comprehensive investigation of the effects of incorporating commonly used fillers into PU membranes individually. Detailed outcomes for each filler are presented, highlighting their respective advantages and disadvantages. Furthermore, a comparative analysis of these fillers is performed to identify specific results efficient for industrial applications and future research. This research contributes to the advancement of MMMs by providing insights into the performance characteristics of different fillers in PU matrices. The findings serve as a valuable resource to optimize gas separation properties of PU‐based membranes and overcome challenges associated with filler integration.
