Although Poly (4-methyl-1-pentene) (PMP) has been extensively used as ECMO material, the problems of protein adsorption fouling and the need for anticoagulation remain challenging for clinical applications. Additionally, the challenges associated with the functional modification of PMP material underscore the importance of finding a new material with excellent gas permeability and blood compatibility. On the other hand, Polymers of Intrinsic Microporosity (PIM) has been extensively studied in the field of gas separation due to their unique twisted helical structure and high free volume. However, its hydrophobic nature also raises concerns about its anti-fouling ability and hemocompatibility, which restricts the exploration of PIM in ECMO applications. Herein, we modify the PIM-1 membrane and study the hemocompatibility of PIM-1, carboxylated-PIM-1, and amidoxime-functionalized-PIM-1, and explore their gas permeability by molecular dynamics simulation and experimental verification. The modified PIM membranes exhibit remarkable comprehensive performance, including effective anti-protein adhesion and hemocompatibility, high oxygen permeability, and CO₂ removal rate. Blood oxygenation tests also reveal that the modified membranes prepared in this work fully meet practical requirements, exhibiting great application potential.</div></div>","PeriodicalId":368,"journal":{"name":"Journal of Membrane Science","volume":"717 ","pages":"Article 123538"},"PeriodicalIF":8.4,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142745480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we developed a series of non-fluorinated PEMs from poly (terphenyl fluorenyl isatin) with fluorene-pendent disulfonate groups. These polymers feature a microblock structure composed of hydrophobic blocks, hydrophilic blocks, and alternating blocks, arising from the differences in reactivity, concentration, and solubility between the hydrophobic p-terphenyl and hydrophilic disulfonated fluorene monomers. As a result, the sulfonic acid groups are unevenly distributed along the polymer chains, forming densely charged regions (IEC = 3.52 meq/g) with large ion clusters and lightly charged regions (IEC = 2.16 meq/g) with small ion clusters. This microstructure, combined with the degree of sulfonation, significantly influences the overall properties of the membranes, including robust mechanical strength (47.1–63.2 MPa), high thermal stability (up to 270 °C), low swelling ratio (18–25 % at 80 °C), and high proton conductivity (136–169 mS/cm in deionized water at 80 °C). The PFLSH60 membrane demonstrated comparable fuel cell performance to Nafion 212.
