Abstract
A multi-layered oil sorbent formed from two superposed polyolefin thin films and a polypropylene (PP) fibrous thin sheet sandwiched between the two superposed polyolefin thin films. Each of the two superposed polyolefin thin films include a plurality of pores defined therethrough and a plurality of swellable cavities extending from a surface thereof. In an embodiment, the cavities of each two superposed polyolefin thin films extend from a respective polyolefin film surface toward the PP fibrous thin sheet. The two superposed polyolefin thin films with the PP fibrous thin sheet sandwiched therebetween are sealed together by a zigzag-shaped heat seal. The plurality of cavities on the surface of the multi-layered sorbent can swell when contacted with oil. The cavities coupled with the zigzag-shaped seal maximize the available volume for uptake of oil and organic pollutants from water.
