In this review paper, we summarize the research progress of TFC membranes in pervaporation applications detailly. Herein, pervaporation fundamentals are briefed, including performance parameters and transport mechanisms involved in liquid-liquid separation and pervaporation desalination. The fabrication methods of support and selective layers, i.e., non-solvent induced phase inversion and electrospunning for the former, as well as interfacial polymerization and layer by layer assembly for the latter are elaborated respectively. Furthermore, the optimization strategies of support and selective layers are also summarized, including material section, filler incorporation, membrane-forming condition, co-solvent assistance, and surface modification. Subsequently, the performance status of TFC membranes is analyzed for various applications, including organic dehydration, organic recovery, and desalination. Finally, the challenges and future perspectives are also presented. We hope that this review can give researchers some guidance for the design and further development of TFC membrane in pervaporation processes.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"1 ","pages":"Article 100008"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823421000099/pdfft?md5=3811e07e78c76ab51edc71395ef8cf9c&pid=1-s2.0-S2772823421000099-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89167413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, aluminum fumarate framework (A520) based mixed matrix hydrogel self-supported membranes (A520-MMHMs) were prepared by a facile UV photopolymerization. The hydrophilic A520 incorporated into hydrogel polymer effectively avoided the formation of interfacial defects and improved the compatibility between MOF and hydrogel matrix. As a result, the A520-MMHM possessed enhanced CO<sub>2</sub> permeability (∼432.87 Barrer) and CO<sub>2</sub>/CH<sub>4</sub> selectivity (∼51.05) in comparison with pure hydrogel membrane. This performance data is very close to the updated McKeown 2019 upper bound, far exceeding the 2008 Robeson upper bound. Therefore, the design of hydrogel membrane incorporated with water-stable MOF may open up a new way for optimizing self-supported hydrogel membrane performance in gas separation.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"1 ","pages":"Article 100009"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823421000105/pdfft?md5=3f3cbc2bb24f3e26b622cc2251846153&pid=1-s2.0-S2772823421000105-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74779352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hollow fiber OSN membranes with defined pore size, reliable stability and durability in various harsh solvents are in urgent demand. Herein, for the first time, braid reinforced hollow fiber (BRHF) OSN membranes with defined pore size, robust mechanical strength, and excellent solvent stability were fabricated and used for the recovery of pharmaceuticals. The BRHF nanofiltration membranes can endure an operation pressure over 3 times larger than that of the cross-linked polyimide hollow fiber OSN membranes in aprotic solvents with a DMF flux of 37.9 LMH and a methanol flux of 70.3 LMH at 15 bar. The membranes show over 98.8% rejection to the Tetracycline, Chlortetracycline hydrochloride and Vitamin B12. After immersion in DMF for 360 h, the membranes maintain over 98% rejection to Chlortetracycline hydrochloride. Moreover, the BRHFs eliminate the risk of module leakage caused by breakage of hollow fibers and surmount the swelling tendency of polymeric OSN membranes in harsh solvents which enables the scaling-up of high-performance hollow fiber OSN membrane modules. The BRHF OSN membranes with robust stability and durability exhibit very promising application prospects in the pharmaceutical and fine chemical industry.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"1 ","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823421000087/pdfft?md5=8bb495eb00d085a29bdffdd19ab1aaa2&pid=1-s2.0-S2772823421000087-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79247995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
