Fluorinated siloxane (F-Si(OCH₃)₃) was synthesized from perfluoro (2-methyl-3-oxyhexyl) fluorine and N- (β-aminoethyl) -γ-aminopropyltrimethoxy silane, and then was used for hydrophobic modification of halloysite nanotubes (F-HNTs). A mixture of epoxy resin and F-HNTs was sprayed onto the surface of the stainless steel mesh. F-HNTs enhanced the surface roughness and reduced the surface energy, giving the mesh superhydrophobic/superlipophilic properties. The static water contact angle of coated mesh can reach 155.4 ± 0.3°. A series of oil and water mixtures can be separated, and the separation efficiency was higher than 97.8 ± 0.3%. After 50 cycles, the separation efficiency was still higher than 96.2 ± 0.5%. The coating mesh also had high separation efficiency for oil-water mixtures with different volume ratios and pH values. More importantly, the coated mesh still showed good stability in the harsh test conditions, such as strong acid, strong alkali, sand-paper wear and so on. Since the preparation of the coated mesh has the advantages of simplicity, scalability, and economy, it is expected to be applied on a large scale in the field of oil-water separation in the future.

氟化硅氧烷 (F-Si(OCH ₃ ) ₃)由全氟(2-甲基-3-氧己基)氟和N-(β-氨基乙基)-γ-氨基丙基三甲氧基硅烷合成，然后用于埃洛石纳米管(F-HNTs)的疏水改性。将环氧树脂和 F-HNT 的混合物喷涂到不锈钢网的表面。F-HNTs 增强了表面粗糙度并降低了表面能，赋予了网状超疏水/超亲油特性。涂层网的静态水接触角可达155.4±0.3°。可分离一系列油水混合物，分离效率高于97.8±0.3%。50次循环后，分离效率仍高于96.2±0.5%。涂层网对不同体积比和pH值的油水混合物也有很高的分离效率。更重要的是，涂层网在强酸、强碱、砂纸磨损等严苛测试条件下仍表现出良好的稳定性。由于涂层网的制备具有简单、可扩展性和经济性等优点，有望在未来在油水分离领域得到大规模应用。
