In this study, based on the hydrophilicity of fullerol (C60(OH)n) and the bacteriostatic properties of silver (Ag), a fullerol\u2013silver (C60(OH)n-Ag) complex was prepared as a multifunctional additive. A polyvinylidene fluoride (PVDF)-composited C60(OH)n-Ag ultrafiltration membrane (C60(OH)n-Ag\/PVDF) was prepared by immersion precipitation phase transformation. Addition of the C60(OH)n-Ag complex improved the permeability and retention of the traditional PVDF membrane. Compared with the traditional PVDF membrane, the surface water contact angle of the modified PVDF and C60(OH)n-Ag ultrafiltration membrane was reduced from 75.05\u00b0 to 34.50\u00b0, its pure water flux increased from 224.11 L\u00b7m\u22122\u00b7h\u22121 to 804.05 L\u00b7m\u22122\u00b7h\u22121, the retention rate on bovine serum protein was increased from 75.00% to 96.44% and the flux recovery rate increased from 64.91% to 79.08%. The C60(OH)n-Ag\/PVDF ultrafiltration membrane had good inhibitory effects on Escherichia coli and Staphylococcus aureus, while the PVDF ultrafiltration membrane had no obvious inhibitory effects.<\/jats:p>","DOI":"10.3390\/polym16233359","type":"journal-article","created":{"date-parts":[[2024,11,29]],"date-time":"2024-11-29T08:24:14Z","timestamp":1732868654000},"page":"3359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Novel PVDF Ultrafiltration Membrane Modified by C60(OH)n-Ag"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4257-696X","authenticated-orcid":false,"given":"Jie","family":"Zhang","sequence":"first","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wenjun","family":"Zhao","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengyang","family":"Shi","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liman","family":"Zhao","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yudi","family":"Chu","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanan","family":"Ren","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qun","family":"Wang","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanxia","family":"Chi","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shujing","family":"Zhou","sequence":"additional","affiliation":[{"name":"Heilongjiang Provincial Key Laboratory of New Drug Development and Pharmacotoxicological Evaluation, Jiamusi University, Jiamusi 154007, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1007\/s10311-018-0785-9","article-title":"Advantages and Disadvantages of Techniques Used for Wastewater Treatment","volume":"17","author":"Crini","year":"2019","journal-title":"Environ.
