Functional superhydrophobic coating has caused intense concern due to its potential applications. A facile and mild dip-coating method is proposed for fabricating superhydrophobic coatings in this work. The epoxy resin (EP) modified by fluorocarbon substituted silsesquioxanes (SQ-F) could be coated on filter paper (FP) and polyurethane sponge (PU), respectively. SQ-F nanoparticles can self-assemble to form multiscale nano-/microstructures during photopolymerization, which improve the hydrophobicity of epoxy. The successful incorporation of SQ-F/EP on filter paper and polyurethane sponge is demonstrated by FT-IR, X-ray photoelectron spectroscopy and energy dispersive spectrometer. SQ-F/EP@FP could separate a series of oil–water mixtures and emulsion effectively with high separation efficiencies over 99.99 %. Furthermore, both liquid pollutant and solid stains are removed by the surface's self-cleaning ability. In comparation with SQ-F/EP@FP, SQ-F/EP@PU with lipophilic and hydrophobic characteristics, possesses oil adsorption capacity about 102 times of its original weight. Moreover, SQ-F/EP@PU could absorb the crude oil within a few minutes and the adsorption capacity reaches as high as 92 times of its original weight.

功能性超疏水涂层由于其潜在的应用而引起了广泛关注。在这项工作中，提出了一种简便、温和的浸涂方法来制备超疏水涂层。氟碳取代倍半硅氧烷(SQ-F)改性环氧树脂(EP)可分别涂敷在滤纸(FP)和聚氨酯海绵(PU)上。SQ-F纳米粒子在光聚合过程中可以自组装形成多尺度纳米/微结构，从而提高环氧树脂的疏水性。FT-IR、X射线光电子能谱和能量色散谱仪证明了SQ-F/EP在滤纸和聚氨酯海绵上的成功掺入。SQ-F/EP@FP可以有效分离一系列油水混合物和乳液，分离效率高达99.99%以上。此外，液体污染物和固体污渍均通过表面的自清洁能力去除。与SQ-F/EP@FP相比，具有亲油和疏水特性的SQ-F/EP@PU具有约102倍于原重量的吸油能力。此外，SQ-F/EP@PU可以在几分钟内吸附原油，吸附能力高达原重量的92倍。
