In this work, we present a size-controlled strategy to fabricate a high-performance mixed matrix membrane (MMM) using poly (vinylamine) (PVAm) matrices incorporated with zeolitic imidazolate framework (ZIF-8) filler (size range: 98–1200 nm). Systematic investigation reveals that ZIF-8 particle size critically governs interfacial compatibility with the PVAm matrix, directly impacting CO₂ separation efficiency. Both significantly larger or smaller particles than 130 nm tend to induce non-selective interfacial voids at the polymer-filler interface. Optimal performance is achieved with 130 nm ZIF-8 fillers, which exhibits superior dispersion stability in PVAm solution, as evidenced by the highest zeta potential value. The resultant MMM exhibits high separation performance under 0.1 MPa feed pressure, achieving a CO₂ permeability of 455.06 GPU and CO₂/N₂ selectivity of 42.36, higher than those of the pure PVAm-based membranes without ZIF-8 filler.

Yet, such validation studies are extremely scarce in the literature, and the vast majority of comparisons between simulated and experimental adsorption isotherms do not realistically consider the inherent uncertainty in either or both methods. In this paper, we conduct a systematic assessment of simulation force fields by comparing them against ‘consensus’ experimental isotherms derived from a curated dataset of carbon dioxide adsorption measurements. Our estimate for the average uncertainty in experimental adsorption isotherms is ∼15 %, while the average uncertainty arising from the choice of framework force field is ∼10 %; these uncertainties are quite significant and should be considered explicitly when comparing simulations to experiments. Remarkably, we observed that generic force fields taken ‘off the shelf’ only yielded good predictions of experimental data for one out of five MOFs studied here – IRMOF-1. The observed discrepancies for Cu-BTC and Co-MOF-74 can be explained by the inability of standard force fields to accurately describe the specific interactions of CO₂ with open metal sites. In contrast, the differences for UiO-66 can be rationalised by the presence of extensive defects in the MOF structure. However, the disagreement observed for MIL-47 has not been unequivocally explained, raising the need for more extensive experimental and simulation studies of this material. Based on these results, we provide concrete recommendations for future computational modelling studies of adsorption in MOFs.</div></div>","PeriodicalId":392,"journal":{"name":"Microporous and Mesoporous Materials","volume":"397 ","pages":"Article 113788"},"PeriodicalIF":4.7,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144773179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
