The dispersion and stability of MWCNT non-covalent functionalized with PEG were all improved. TEM characterization and XPS quantitative analysis proved that the use of PEG to non-covalent functionalize MWCNT was successful. SEM image analysis confirmed that the pore size of PEG\u2013MWCNT membrane was more concentrated and distributed in a narrower range of diameter. Contact angle measurement demonstrated that PEG non-covalent functionalization greatly enhanced the hydrophilicity of MWCNT membranes. The results of pure water flux showed that the PEG\u2013MWCNT membranes could be categorized into low pressure membrane. PEG-MWCNT membrane had a better effect on the removal of humic acid (HA) and a lower TMP growth rate compared with a commercial 0.01-\u03bcm PVDF ultrafiltration membrane. During the filtration of bovine serum albumin (BSA), the antifouling ability of PEG-MWCNT membranes were obviously better than the raw MWCNT membranes. The TMP recovery rate of PEG\u2013MWCNT membrane after cross flushing was 79.4%, while that of raw MWCNT\u2013COOH and MWCNT membrane were only 14.9% and 28.3%, respectively. PEG non-covalent functionalization improved the antifouling ability of the raw MWCNT membranes and reduced the irreversible fouling, which effectively prolonged the service life of MWCNT membrane.<\/jats:p>","DOI":"10.3390\/membranes11050362","type":"journal-article","created":{"date-parts":[[2021,5,17]],"date-time":"2021-05-17T12:19:57Z","timestamp":1621253997000},"page":"362","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Preparation of Ultrafiltration Membrane by Polyethylene Glycol Non-Covalent Functionalized Multi-Walled Carbon Nanotubes: Application for HA Removal and Fouling Control"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5990-2189","authenticated-orcid":false,"given":"Yu","family":"Wang","sequence":"first","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengchan","family":"Dong","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinya","family":"Xiong","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoli","family":"Gai","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Zeng","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guirong","family":"Luan","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yufei","family":"Wang","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaochen","family":"Wu","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Guo","sequence":"additional","affiliation":[{"name":"National Engineering Laboratory for Advanced Municipal Wastewater Treatment and Reuse Technology, Beijing University of Technology, Pingleyuan No.100, Beijing 100124, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"362","DOI":"10.1016\/j.memsci.2017.06.077","article-title":"Hydraulic backwashing for low-pressure membranes in drinking water treatment: A review","volume":"540","author":"Chang","year":"2017","journal-title":"J.
