N2 - Oil pollution of waters is one of the most serious environmental problems globally. The long half-life and
persistence within the environment makes oil particularly toxic and difficult to remediate. There is a
significant need for efficient and cost-effective oil recovery technologies to be brought in to practice. In
this study, we developed a facile and efficient magnetic separation method. The surface of 316L stainless
steel nanoparticles was modified by plasma deposition of 1,7-octadiene and perfluorooctane, producing
relatively hydrophobic coatings having water contact angles of 86 and 100, respectively. Both coatings
had high oil removal efficiency (ORE) of >99%. The captured oil could be easily separated by applying an
external magnetic force. The ease of material preparation and separation from the water after the oil is
captured, and its high ORE is a compelling argument for further development and optimization of the
technology to possible utilization into practice. Furthermore, the capacity of plasma polymerization to
deliver desired surface properties can extend the application of the technology to removing other
chemical and biological contaminants from polluted waters.
