제목 An anti-overturn Janus sponge with excellent floating stability for simultaneous pollutant remediation and oil/water separation
초록 Harsh marine conditions such as high waves and winds prevent effective oil/water separation and reduce the level of separation performance that is obtained in the laboratory. For real applications of marine pollution remediation, an anti-overturn Janus sponge (AJS) that partially floats/is partially submerged on/under water was prepared. The Janus characteristic originates from the cooperative effect of the hydrophilic part absorbing water and the hydrophobic part generating buoyancy. The AJS showed excellent floating stability under high waves and winds. The AJS also exhibited high adsorption of aqueous pollutants during oil/water separation, stably remained at the oil/water and water/oil interfaces in three liquid multiphases and removed aqueous pollutants at each interface. Additionally, a pant-like structure that was divided into two branches could successively separate three liquid multiphases (light oil/water/heavy oil) and quickly purify contaminated water during the separation.
