Abstract
A medium for fast, selective oil-water separation and/or oil absorption includes steel wool modified with a polymer a polymer or a polymer mixture. The polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water. The polymer or the polymer mixture includes polydimethylsiloxane, polytetrafluoroethylene, polyvinylpyrrolidone, or a combination thereof. The solution immersion method used to synthesize the medium requires only a single, simple step and affordable materials and, as a result, is easy to scale up.
