摘要：

Water resources polluted by oil seriously affect human health and ecosystem. In order to obtain materials with excellent oil-water separation performance, assembling nanometre silver thin layer on the surface of cotton fabric by layer self-assembly method, and modified it with dodecyl mercaptan, then cotton fabric with superhydrophobic-superoleophilic performance is prepared. The microstructure, surface chemical composition, wettability and oil-water separation performance of superhydrophobic- superlipophilic cotton fabric are characterized by scanning electron microscope, X-ray diffractometer, contact angle tester and separation efficiency. The modified cotton fabric is loaded up with dense nano silver layers, the water contact angle is up to 160° and the oil contact angle is 0° on the surface, showing excellent superhydrophobic-superlipophilic performance. Nano-silver is firmly attached to the surface of cotton fabric, showing fine wear resistance and corrosion resistance. The oil-water separation test shows that the cotton fabric not only have a good recycling ability, but also having separation efficiency of different types of oil and water mixtures, and separation efficiency is over 88%. In addition, the cotton fabric can not only separate light oil on water and water sinking oil from water, but also can separate the mixture formed by three phases of light oil-water-sinking oil. © 2021, Materials Review Magazine.
