In this Letter, we have fabricated a multifunctional device for highly efficient and inexpensive oil spill cleanup by combining electroless metal deposition with self-assembled monolayers, which has integrated the functions of oil containment booms, oil-sorption materials, oil skimmers, and water-oil separating devices. This functionally integrated device has a lower density than that of water, which leads to a potential application as oil containment booms; it can take up oil that is 3.5 times its own weight, which shows excellent oil-sorption properties, with the water-oil separating yield of the as-prepared device being up to 92%. The device has the advantages of high efficiency, capacity of antiwave, and reproducibility, which is suitable for many types of organic solvents or oils, even for emulsion of petroleum and water, and thus is a proof-of-principle idea to be applied in marine spilt oil cleanup and other water-oil separating systems.
在这封信件中，我们通过将化学镀与自组装单分子层相结合，制造出一种多功能设备，用于高效且廉价地进行溢油清理，该设备集成了围油栏、吸油材料、撇油器和油水分离装置的功能。这种功能集成的设备密度小于水，因此有可能用作围油栏；它可以吸收自身重量 3.5 倍的油，表现出优异的吸油性能，所制备的设备的油水分离率高达 92%。该设备具有高效、抗波浪和可重复使用的优点，适用于多种有机溶剂或油，甚至是石油和水的乳液，因此是一种应用于海洋溢油清理和其他油水分离系统的原理验证理念。
