With the further development of petroleum transportation, oil spills are becoming increasingly frequent and the leakage environment is becoming more and more complex. In order to cope with this trend, an oil adsorption material that combined magnetic and photothermal conversion functions was prepared in this study. Through experimental research, it can be found that the prepared material had a high porosity, and its skeleton surface was uniformly coated with Fe3O4 nanoparticle, graphene and PDMS. The adsorbent had excellent hydrophobicity and oleophilicity, and could efficiently recover oil substances in water. The adsorption capacity of the material for different oil substances was between 28.4–62.9 g/g. At the same time, the adsorbent also had magnetism and could be easily lifted by magnets. In addition, the adsorbent also possessed excellent photothermal conversion efficiency, and could adsorb crude oil with high viscosity under simulated sunlight irradiation. From the above conclusion, it can be concluded that this material has broad prospects in the field of oil spill treatment.

摘要

With the further development of petroleum transportation, oil spills are becoming increasingly frequent and the leakage environment is becoming more and more complex. In order to cope with this trend, an oil adsorption material that combined magnetic and photothermal conversion functions was prepared in this study. Through experimental research, it can be found that the prepared material had a high porosity, and its skeleton surface was uniformly coated with Fe3O4 nanoparticle, graphene and PDMS. The adsorbent had excellent hydrophobicity and oleophilicity, and could efficiently recover oil substances in water. The adsorption capacity of the material for different oil substances was between 28.4–62.9 g/g. At the same time, the adsorbent also had magnetism and could be easily lifted by magnets. In addition, the adsorbent also possessed excellent photothermal conversion efficiency, and could adsorb crude oil with high viscosity under simulated sunlight irradiation. From the above conclusion, it can be concluded that this material has broad prospects in the field of oil spill treatment.
