    Abstract

    The treatment of oily wastewater has become a worldwide problem. How to effectively separate the oil-water mixture has become an urgent problem to be solved. Here, the environmental friendly and simple dipping surface modification method was used to modify the melamine sponge (MS) by using a mixture of graphene oxide (GO) and polytetrafluoroethylene (PTFE), and superhydrophobic material (GPMS) was successfully prepared. Structure, morphology and composition of the obtained GPMS were analyzed by X-ray diffraction (XRD), thermogravimetric (TG), Fourier transform infrared spectroscope (FT-IR), and scanning electron microscope (SEM). Its surface wettability, compression cycle, selective adsorption performance, and continuous oil-water emulsion separation performance were systematically studied. The results show that the GPMS is superhydrophobic with hydrophobic angle up to 168°. It can undertake 50 compression cycles, selectively adsorb both floating oil and underwater heavy oil, and efficiently separate oil-water emulsion. Therefore, the GPMS is a kind of potentially applicative oil pollution control material.
