Abstract

Membrane separation technology is gaining increasing prominence, particularly for CO₂ removal in natural gas upgrading and flue gas treatment. Rubbery polymers feature soft, flexible segments that allow unrestricted rotation around the main chain, exhibit molecular flexibility that increases fractional free volume, leading to enhanced gas permeability. This review provides a comprehensive summary of recent innovations in state-of-the-art rubbery polymers for high-performance CO₂ separation membranes, which are advancing this technology toward its theoretical limits, with a focus on developments over the past five years. It emphasizes polymer modifications such as blending, cross-linking, and surface functionalization. Although these strategies remain underexplored, promising results have emerged in CO₂-selective mixed matrix membranes incorporating fillers such as Zeolitic Imidazolate Frameworks (ZIFs), University of Oslo (UiOs), Materials of Institute Lavoisier (MILs), emerging MOF-based and 2D fillers. The common challenges associated with 2D and 3D-based fillers have been systematically summarized. Additionally, the scalability of these technologies from flat sheet to thin film composite hollow fiber membranes which provides energy efficiency suitable for large-scale integration have been discussed. In conclusion, this review identifies key research gaps and future directions to drive innovation in rubbery polymer membranes for CO₂ capture.

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
