| 英文摘要 | A superhydrophobic and superoleophilic Ni mesh decorated with Ni3S2 nanorods (NRs) has been prepared via facile hydrothermal route and 1-octdecanethiol (ODT) surface modification processes. Ni3S2 can be grown directly onto Ni mesh and the length of nanorods can be easily controlled by changing the hydrothermal treatment time. After modified by ODT, the excellent superhydrophobicity of as-prepared mesh combines the roughness of Ni3S2 nanorods with the low surface energy of ODT, which is mechanically durable and chemically stable. The optimum sample by 6 h-hydrothermal treatment and subsequent ODT modification presents a water contact angle of 151 degrees and a sliding angle of 11 degrees. It allows various types of oils and organic liquids to penetrate through but repels water. High separation efficiencies > 94% for five oil-water mixtures are achieved by using a simple self-built oil-water separation device based on the superhydrophobic mesh. After 10 cycles, high separation efficiency can still be retained. It is worth noticed that the mesh can retain its high separation efficiency even after soaking in 3.5% NaCl solution for 2 days. Besides, the superhydrophobic mesh shows good resistance to strong alkaline solution but poor resistance to strong acid solution. The unique, durable, and superhydrophobic/ superoleophilic mesh exhibits wide application prospect in the industrial fields of oil-water separation. |
