Abstract How to treat the pollution caused by oily wastewater has become a serious worldwide problem. The shortcomings of traditional oil-water separation materials in terms of performance, cost, and preparation have limited their application in practice. Therefore, exploration of novel oil-water separation materials with excellent performance, low cost, and simple preparation have attracted widespread attention. In this work, a novel coating (AC/PTFE) was firstly prepared by mixing activated carbon (AC) powder with polytetrafluoroethylene concentrated dispersion (PTFE). Then melamine sponge (MS) was dip-coated with this coating, and after a simple heat treatment process, the three-dimensional oil-water separation material (AC/PTFE-MS) was prepared. The performance test results show that AC/PTFE-MS is superhydrophobic (water contact angle up to 165°), and this property can maintain even after 300 extrusions. Meanwhile, AC/PTFE-MS has high adsorption capacity and can also selectively adsorb oil or organic pollutants from water. Moreover, it can also efficiently separate oil-water emulsion. Thus, this three-dimensional oil-water separation material has application value in the actual oily wastewater treatment.

Key words： oil/water separation melamine sponge superhydrophobic emulsion coating
