Inspired by the strong adhesion of mussels, a super-hydrophobic sponge was designed and prepared by a simple and inexpensive one-pot solution immersion method. The prepared superhydrophobic sponge can not only efficiently separate the oil–water mixture, more importantly, but also remove volatile organic compounds in the atmospheric environment. Polydopamine (PDA) enables polydivinylbenzene (PDVB) particles to be firmly and tightly attached to the melamine sponge skeleton, thereby making the hydrophilic sponge superhydrophobic and providing adsorption sites for volatile organic compounds in the air. The synergy enables the sponge/PDA/PDVB to quickly adsorb oils and organic substances, and it has high stability and capacity even after 20 cycles. In addition, superhydrophobic sponges can still perform outstanding adsorption performance even under highly acidic and alkaline environments. Meanwhile, the static adsorption capacity of the sponge/PDA/PDVB for gaseous toluene is 5.7 times that of activated carbon. Compared with pure PDVB, the super-hydrophobic sponge in the dynamic experiment has a penetration time increased from 6 to 390 min, which is 65 times longer than that of the PDVB, and the adsorption performance has been greatly improved. Therefore, our strategy may achieve a new effect, which can quickly and easily separate oil–water mixtures and remove volatile gaseous pollutants, and it can provide potential options for practical applications

受到贻贝的强粘附力的启发，通过一种简单且便宜的单锅溶液浸泡方法设计并制备了一种超疏水海绵。制备的超疏水海绵不仅可以有效地分离油水混合物，更重要的是，还可以去除大气环境中的挥发性有机化合物。聚多巴胺（PDA）使聚二乙烯基苯（PDVB）颗粒牢固牢固地附着在三聚氰胺海绵骨架上，从而使亲水性海绵具有超疏水性，并为空气中的挥发性有机化合物提供了吸附位置。协同作用使海绵/ PDA / PDVB能够快速吸附油和有机物质，即使经过20个循环，它仍具有很高的稳定性和容量。此外，即使在强酸和强碱的环境下，超疏水海绵仍然可以发挥出色的吸附性能。同时，海绵/ PDA / PDVB对气态甲苯的静态吸附能力是活性炭的5.7倍。与纯PDVB相比，动态实验中的超疏水海绵的渗透时间从6分钟增加到390分钟，是PDVB的65倍，并且吸附性能得到了极大的提高。因此，我们的策略可能会取得新的效果，可以快速轻松地分离油水混合物并去除挥发性气态污染物，并且可以为实际应用提供潜在的选择 活性炭的7倍。与纯PDVB相比，在动态实验中，超疏水海绵的渗透时间从6分钟增加到390分钟，是PDVB的65倍，并且吸附性能大大提高。因此，我们的策略可能会取得新的效果，可以快速轻松地分离油水混合物并去除挥发性气态污染物，并且可以为实际应用提供潜在的选择 活性炭的7倍。与纯PDVB相比，在动态实验中，超疏水海绵的渗透时间从6分钟增加到390分钟，是PDVB的65倍，并且吸附性能大大提高。因此，我们的策略可能会取得新的效果，可以快速，轻松地分离油水混合物并去除挥发性气态污染物，并且可以为实际应用提供潜在的选择
