Superhydrophobic materials are widely utilized to separate oil from water. Proposing a facial method to synthesis a durable hydrophobic/superhydrophobic surface for efficient and easy oil/water separation is necessary due to the danger of oil spills for ecosystems. Herein, a robust superhydrophobic filter is introduced for oil/water separation. Organosilica nano/microstructures covered resorcinol-formaldehyde resin are loaded on the copper mesh surface to earn a roughened surface then modified by 1-dodecanethiol to get a low surface energy mesh. The prepared superhydrophobic copper mesh was shaped to a basket-like as an oil skimmer device that repels the water and collects the oil through its pores. The sample was analyzed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, atomic force microscopy and X-ray photoelectron spectroscopy methods. The sample exhibits high water contact angle, θ=149±1° and the oil contact angle, showing its superhydrophobic nature. The prepared superhydrophobic mesh was used as an efficient and robust filter to separate oil from water. Its oil/water separation efficiency is more than 90% and this value approximately preserves after 50 cycles. The prepared sample also shows self-cleaning property. Thanks to the stable and rough structured created by resorcinol-formaldehyde resin covered by organosilica particles and also the low surface energy provided by 1-dodecanethiol, the prepared sample shows superhydrophobic property with high efficiency to separate oil from water.

超疏水材料被广泛用于分离油和水。由于石油泄漏对生态系统的危险，因此有必要提出一种面部方法来合成耐用的疏水/超疏水表面，以实现高效和轻松的油/水分离。在此，引入了一种强大的超疏水过滤器用于油/水分离。将有机二氧化硅纳米/微结构覆盖的间苯二酚-甲醛树脂负载在铜网表面上以获得粗糙的表面，然后用 1-十二烷硫醇改性以获得低表面能网。制备的超疏水铜网被塑造成篮子状作为撇油装置，排斥水并通过其孔收集油。样品通过扫描电子显微镜、能量色散 X 射线光谱、原子力显微镜和 X 射线光电子能谱方法。样品表现出高水接触角，θ=149±1°和油接触角，显示其超疏水性。制备的超疏水网被用作一种高效且坚固的过滤器，以将油与水分离。其油水分离效率达90%以上，该值在50次循环后约保持不变。制备的样品还显示出自清洁性能。由于由有机二氧化硅颗粒覆盖的间苯二酚-甲醛树脂产生的稳定和粗糙的结构以及1-十二烷硫醇提供的低表面能，制备的样品显示出超疏水性，可高效分离油水。显示其超疏水性。制备的超疏水网被用作一种高效且坚固的过滤器，以将油与水分离。其油水分离效率达90%以上，该值在50次循环后约保持不变。制备的样品还显示出自清洁性能。由于由有机二氧化硅颗粒覆盖的间苯二酚-甲醛树脂产生的稳定和粗糙的结构以及1-十二烷硫醇提供的低表面能，制备的样品显示出超疏水性，可高效分离油水。显示其超疏水性。制备的超疏水网被用作一种高效且坚固的过滤器，以将油与水分离。其油水分离效率达90%以上，该值在50次循环后约保持不变。制备的样品还显示出自清洁性能。由于由有机二氧化硅颗粒覆盖的间苯二酚-甲醛树脂产生的稳定和粗糙的结构以及1-十二烷硫醇提供的低表面能，制备的样品显示出超疏水性，可高效分离油水。制备的样品还显示出自清洁性能。由于由有机二氧化硅颗粒覆盖的间苯二酚-甲醛树脂产生的稳定和粗糙的结构以及1-十二烷硫醇提供的低表面能，制备的样品显示出超疏水性，可高效分离油水。制备的样品还显示出自清洁性能。由于由有机二氧化硅颗粒覆盖的间苯二酚-甲醛树脂产生的稳定和粗糙的结构以及1-十二烷硫醇提供的低表面能，制备的样品显示出超疏水性，可高效分离油水。
