Robust Superhydrophobic Sepiolite-Coated Polyurethane Sponge for Highly Efficient and Recyclable Oil Absorption

With the rapid increase of oil production and offshore transportation, the probability of accidental oil leakage is rising. Utilization of superhydrophobic materials constitutes an effective method to solve oil pollution on the water surface. In this study, a modified superhydrophobic sepiolite (SEP) layer was loaded onto the skeleton surface of three-dimensional (3D) porous polyurethane (PU) sponges through a one-step ultrasonic dip-coating...
