Membranes of Polymer of Intrinsic Microporosity PIM-1 for Gas Separation: Modification Strategies and Meta-Analysis

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Jan. 23, 2025

Abstract Polymers of intrinsic microporosity (PIMs) have received considerable attention for making high-performance membranes carbon dioxide separation over the last two decades, owing to their highly permeable porous structures. However, challenges regarding its relatively low selectivity, physical aging, and plasticisation impede relevant industrial adoptions gas separation. To address these issues, several strategies including chain modification, post-modification, blending with other polymers, addition fillers, been developed explored. PIM-1 is most investigated PIMs, hence here we review state-of-the-arts modification critically discuss progress achieved addressing aforementioned via meta-analysis. Additionally, development PIM-1-based thin film composite commented as well, shedding light on potential in We hope that can be a timely snapshot PIMs guiding future design optimisation PIMs-based enhanced performance towards higher technology readiness level practical applications.

Metal-organic cages improving microporosity in polymeric membrane for superior CO ₂ capture

Science Advances, Journal Year: 2025, Volume and Issue: 11(4)

Published: Jan. 22, 2025

Mixed matrix membranes, with well-designed pore structure inside the polymeric via incorporation of inorganic components, offer a promising solution for addressing CO 2 emissions. Here, we synthesized series novel metal organic cages (MOCs) aperture size precisely positioned between and N or CH 4 . These MOCs were uniformly dispersed in polymers intrinsic microporosity (PIM-1). Among them, MOC-Ph cage effectively modulated chain packing optimized microporous membrane. Remarkably, PIM-Ph-5% membrane shows superior performance, achieving an excellent permeability 8803.4 barrer /N selectivity 59.9, far exceeding 2019 upper bound. This approach opens opportunities improving porous membranes capture other separation applications.

Substantially Improving CO₂ Permeability and CO₂/CH₄ Selectivity of Matrimid Using Functionalized-Ti₃C₂T_x

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 2, 2025

Mixed-matrix membranes (MMMs) with favorable interfacial interactions between dispersed and continuous phases offer a promising approach to overcome the traditional trade-off permeability selectivity in membrane-based gas separation. In this study, we developed free-standing MMMs by embedding pristine surface-modified Ti3C2Tx MXenes into Matrimid 5218 polymer for efficient CO2/CH4 Two-dimensional adjustable surface terminations provided control over these critical interactions. Characterization (Raman spectroscopy, XPS, DSC, FTIR) indicated formation of hydrogen bonds termination groups on carbonyl Matrimid, promoting enhanced compatibility dispersion within matrix. The resulting 5 wt % showed 67% increase CO2 an 84% enhancement compared membranes. Surface modification using [3-(2-aminoethylamino)propyl]trimethoxysilane (AEAPTMS) further compatibility, leading 140% higher 130% greater selectivity. Molecular simulations suggested that AEAPTMS functionalization improved chains, increasing affinity toward molecules. Additionally, elongation pathways, chain disruption, presence interlayer nanogalleries contributed positively separation performance. This work provides insights tailoring nanomaterial–polymer interfaces address challenges separation, paving way environmentally friendly technologies.
