Abstract
tSeeking eco-friendly, highly-efficient, low-cost, and robust adsorbents to remove oil from water resourcesare very much in demand. In this work, an environmentally friendly, recyclable, superhydrophobic, andsuperoleophilic seashell/epoxy resin/polyurethane (EP/SPU) sponge with contact angle of 174.10 ± 0.47◦was prepared. EP/SPU sponge demonstrated high adsorption capacity in the range of 28.03–42.17 g/gtimes more than of its own weight for five oils and four organic solvents. The EP/SPU sponge was used 10times for the adsorption of the oils and organic solvents with no significant loss in its adsorption capacity.The mechanical test suggested that the lightweight EP/SPU sponge is not compressible compared withneat polyurethane (PU) sponge. The volume of neat PU sponge decreased from 2.28 to 1.14 cm3whilethe EP/SPU sponge volume (2.28 cm3) did not change. As a result, EP/SPU sponge is expected to be apromising sorbent for potential applications in the cleanup of oil spills from water.
