In order to improve the high temperature resistance, in this work, a polyamide TFC RO membrane with covalent organic frameworks (COFs) intermediate layer was prepared. Firstly, the COFs layer was decorated on polyether sulfone (PES) support membrane by a unidirectional diffusion method and further modified for shrinking the micropore via the chemical crosslinking reaction with 1,3-diamino-2-propanol (DAPL) or ethylenediamine (EDA), and then continued the conventional interfacial polymerization of m-phenylene diamine (MPD) and trimesoyl chloride (TMC) on the resultant COFs layer for preparing the RO membrane. Furthermore, the correlationship between the microstructure of COFs layer and the separation performance of modified RO membrane was systematically investigated. Due to the introduction of the COF_TpPa-DAPL intermediate layer with more regular microstructure and specific hydrophilicity, the resultant TFC-COF_TpPa-DAPL RO membrane exhibited improvement in water flux by 30 ​% (reached to 50.5 ​L ​m⁻² ​h⁻¹) and higher salt rejection (&gt;99.5 ​%) as compared with the conventional polyamide RO membrane and other reported temperature resistance RO membranes. Meanwhile, this TFC-COF_TpPa-DAPL membrane showed good long-term separation stability during the RO process for 160 ​h. Especially, its water flux increased to 98.8 ​L ​m⁻² ​h⁻¹ without weakening salt rejection (about 99.4 ​%) at 70 ​°C. This study provides an effective way to fabricate the high temperature resistance TFC polyamide RO membrane with good comprehensive separation performance based on COFs intermediate layer.</p></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"4 ","pages":"Article 100101"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772823424000125/pdfft?md5=26ba80f780e2650ca2c3cdc609b0660b&pid=1-s2.0-S2772823424000125-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141985309","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}

However, there are still difficulties in the easy and reliable preparation of scalable and highly permeable COPs membranes. In this work, the polyaminophenylene (PAP) layer was constructed on polysulfone (PSF) ultrafiltration membranes by diazonium-induced anchoring process (DIAP), and then used as a substrate to prepare ultra-thin and highly permeable COPs NF membranes by interfacial polymerization (IP) in only 20 ​s. The presence of PAP layer increases the aqueous phase monomer storage to promote the forward progression and limits the reaction zone of IP, thus resulting in ultrathin and highly crosslinked COPs membranes. In addition, the PAP layer covalently grafted onto the PSF molecular chain also participates in the IP reaction, thus the separation layer is connected to the substrate as a whole for better stability and can operate for long periods of time in an alcohol-based organic solvent environment. The methanol permeance of optimal NF-PAP membrane prepared based on the above strategy can reach 362-398 ​L⁻¹m⁻²h⁻¹bar⁻¹, which almost achieves an order of magnitude enhancement relative to other reported COPs organic solvent nanofiltration (OSN) membranes. The retention rate of the COPs composite membrane for naphthol green B (Mw ​= ​878) dye was about 98.5 ​%, demonstrating good alcohol recovery ability.
