| Popis: | Industrial oil spills in various bodies of water is a worldwide environmental problem that requires effective oil absorbents with remote controllability, which would be a clear improvement upon currently used technologies. One approach for adding remote controllability is embedding magnetic particles into the oil absorbent materials; however, there are currently few reports of magnetic oil absorbents. Most of these are prepared through multistep processes or using hazardous materials, which inhibits their practical use. In this study, we introduce a single-step dipping method to simultaneously provide both magnetic and hydrophobic/oleophilic functions to melamine foam by combining hydrophobic flexible copolymer poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and magnetic Fe3O4 nanoparticles synthesized by a method suitable for mass production. The as-fabricated coating performs effectively for oil collection of oil spilled on water, and the movement of the foam on the water’s surface can be ef... |
