【 摘 要 】

In recent years, the frequent occurrence of oil spills has been a serious threat to marine and aquatic ecosystems. The environmental and economic demands also emphasize the need for materials which can effectively separate oil and water. In order to handle these environmental issues caused by oil spills, all kinds of oil-water separation methods have been developed. In this work, we have fabricated a thermosensitive device with a simple and versatile method: we sprayed the spray adhesive onto a stainless steel mesh box, then amino-P25 nanoparticles were sprayed onto the device directly. Finally, PNIPAM was synthesized on the surface of device. The wettability of PNIPAM modified separation device can be controlled by temperature and finally a 3-phase oil-water-oil continuous separation was realized.
