Therefore, efficient materials and processes for effective oil\u2013water separation are being developed. Herein, SiO2-Na2SiO3-coated stainless steel fibers (SSF) with underwater superoleophobic and low-adhesion properties were successfully prepared via a one-step hydrothermal process. The modified surfaces were characterized with scanning electron microscopy (SEM), and contact angle measurements to observe the surface morphology, confirm the successful incorporation of SiO2, and evaluate the wettability, as well as with X-ray diffraction (XRD). The results revealed that SiO2 nanoparticles were successfully grown on the stainless-steel fiber surface through the facile hydrothermal synthesis, and the formation of sodium silicate was detected with XRD. The SiO2-Na2SiO3-coated SSF surface exhibited superior underwater superoleophobic properties (153\u2013162\u00b0), super-hydrophilicity and high separation efficiency for dichloromethane\u2013water, n-hexane\u2013water, tetrachloromethane\u2013water, paroline\u2013water, and hexadecane\u2013water mixtures. In addition, the as-prepared SiO2-Na2SiO3-coated SSF demonstrated superior wear resistance, long-term stability, and re-usability. We suggest that the improved durability may be due to the presence of sodium silicate that enhanced the membrane strength. The SiO2-Na2SiO3-coated SSF also exhibited desirable corrosion resistance in salty and acidic environments; however, further optimization is needed for their use in basic media. The current study presents a novel approach to fabricate high-performance oil\u2013water separation membranes.<\/jats:p>","DOI":"10.3390\/ma14102628","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T00:06:54Z","timestamp":1621296414000},"page":"2628","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Synthesis of Si-Based High-Efficiency and High-Durability Superhydrophilic-Underwater Superoleophobic Membrane of Oil\u2013Water Separation"],"prefix":"10.3390","volume":"14","author":[{"given":"Xiao-Hui","family":"Fang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"},{"name":"Key Laboratory of Advanced Materials of Tropical Island Resources of Ministry of Education, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su-Hui","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lan-Lin","family":"Yi","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"},{"name":"Key Laboratory of Advanced Materials of Tropical Island Resources of Ministry of Education, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong-Bin","family":"Yin","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"},{"name":"Key Laboratory of Advanced Materials of Tropical Island Resources of Ministry of Education, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong-Jun","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Jiu","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Resource Utilization in South China Sea, Special Glass Key Lab of Hainan Province, Hainan University, Haikou 570228, China"},{"name":"Key Laboratory of Advanced Materials of Tropical Island Resources of Ministry of Education, Haikou 570228, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"157421","DOI":"10.1016\/j.jallcom.2020.157421","article-title":"Hierarchical WO3@Cu(OH)2 nanorod arrays grown on copper mesh with superwetting and self-cleaning properties for high-performance oil\/water separation","volume":"855","author":"He","year":"2021","journal-title":"J.
