Abstract BACKGROUND Increased concentration of carbon dioxide (CO 2 ) emission leads to climate change. Hollow‐fibre membrane technology seems feasible due its high packing density, facile processability and easily tuneable properties. A mixed matrix is designed overcome the balance solution–dissolution phenomena. However, ensuring optimized dispersion fillers at outermost selective skin layer region appears be challenging. In this study, a thin‐film composite (TFCMMM) fabricated with dip‐coating method comprising PES substrate, polydimethylsiloxane (PDMS) coating magnesium oxide (MgO) nanosheet as additive filler in layer. RESULTS The loading MgO was varied from 0 10 wt% PDMS solution. Mixed gas performance showed similar trend single permeation test, lower permeance selectivity effect competitive sorption between binary mixtures. permeance–selectivity trade‐off absent until 1.00 wt%, when CO /N /CH 4 improved by 35.13% 27.55%, respectively, over pristine TFCMMM. When increased beyond 2.5 agglomeration leaching caused formation non‐selective voids, reducing selectivity. improvement observed study an tortuous pathway penetrant presence high‐aspect‐ratio nanosheet, resulting slower diffusion through CONCLUSION Our findings provide additional insights into fabrication TFCMMM using layer, specifically for separation. © 2025 Society Chemical Industry (SCI).
