Abstract Oil slick collection is an important way to treat oil-bearing wastewater and oil spill discharge. Superhydrophobic materials have attracted increasing attention in oil-water separation. An interesting method of constructing superhydrophobic meshes was presented. A mesh was coated with nanoscale SiO2 particles via electro-spray deposition to form microstructure mesh, which was then modified by odecyltrimethoxysilane to be superhydrophobic and superlipophilic. The whole construction process was easy without the requirement of complex equipment or chemical reagents. Stainless steel mesh, copper mesh and acrylic mesh were treated to be superhydrophobic. The oil slick collection rate reached 95% with high oil flow. The constructed superhydrophobic mesh could work at high temperature, low temperature or salty solution. After 20 times of use, the superhydrophobic meshes maintained a high collection rate. The significant advantages of this method are the ability to be free from material constraints, high collection rate and environmental friendliness, showing great application potential.

通过电喷雾沉积纳米级 SiO2 涂层超疏水网格用于油水分离

摘要 浮油收集是处理含油废水和溢油排放的重要方式。超疏水材料在油水分离领域受到越来越多的关注。提出了一种构建超疏水网格的有趣方法。通过电喷雾沉积将纳米级 SiO2 颗粒涂覆在网格上形成微结构网格，然后用十二烷基三甲氧基硅烷将其改性为超疏水和超亲油。整个施工过程简单，不需要复杂的设备或化学试剂。不锈钢网、铜网和亚克力网被处理为超疏水性。在高油流量下，浮油收集率达到95%。构建的超疏水网格可以在高温、低温或咸溶液中工作。使用20次后，超疏水网格保持高收集率。该方法的显着优点是不受材料限制、收集率高、环境友好，显示出巨大的应用潜力。
