In this work, a series of copper foams with superhydrophobicity and superoleophilicity were chemically etched using 10 mg mL\u22121 FeCl3\/HCl solution with consequent ultrasonication, followed by the subsequent modification of four sulfhydryl compounds. A water contact angle of 158\u00b0 and a sliding angle lower than 5\u00b0 were achieved for the copper foam modified using 10 mM n-octadecanethiol solution in ethanol. In addition, the interaction mechanism was initially investigated, indicating the coordination between copper atoms with vacant orbital and sulfur atoms with lone pair electrons. In addition, the polymeric fibers were electrospun through the dissolution of polystyrene in a good solvent of chlorobenzene, and a nonsolvent of dimethyl sulfoxide. Oil absorption and collection over the water surface were carried out by the miniature boat made out of copper foam, a string bag of as-spun PS fibers with high oil absorption capacity, or the porous boat embedded with the as-spun fibers, respectively. The findings might provide a simple and practical combinational method for the solution of oil spill.<\/jats:p>","DOI":"10.3390\/polym11010097","type":"journal-article","created":{"date-parts":[[2019,1,9]],"date-time":"2019-01-09T03:06:06Z","timestamp":1547003166000},"page":"97","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Facile Fabrication of Superhydrophobic Copper- Foam and Electrospinning Polystyrene Fiber for Combinational Oil\u2013Water Separation"],"prefix":"10.3390","volume":"11","author":[{"given":"Yu-Ping","family":"Zhang","sequence":"first","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing-Hua","family":"Yang","sequence":"additional","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"},{"name":"Hunan Academy of Agricultural Sciences, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling-Li","family":"Li","sequence":"additional","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng-Xing","family":"Cui","sequence":"additional","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1708-4362","authenticated-orcid":false,"given":"Ying","family":"Li","sequence":"additional","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shan-Qin","family":"Liu","sequence":"additional","affiliation":[{"name":"Henan Institute of Science and Technology, Xinxiang 453000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-Mao","family":"Zhou","sequence":"additional","affiliation":[{"name":"Hunan Academy of Agricultural Sciences, Changsha 410128, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ling-Bo","family":"Qu","sequence":"additional","affiliation":[{"name":"College of Chemistry and Molecular Engineering, Zhengzhou University, Henan 450001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1016\/j.matdes.2018.01.027","article-title":"Design and Preparation of Efficient, Stable and Superhydrophobic Copper Foam Membrane for Selective Oil Absorption and Consecutive Oil\u2013water Separation","volume":"142","author":"Rong","year":"2018","journal-title":"Mater.
