Oil sorbents are widely used to minimize the severe damage caused by an oil spill. Among them, linear low-density polyethylene (LLDPE) based films showed unique advantages including selective absorption of oil from water and ease of post-processing. However, the dense structure often hinders the penetration of viscous oil and recovery of absorbents is difficult. In this work, we present a LLDPE-based fibrous matrix prepared via electrospinning for highly efficient removal of viscous oils. The fibrous form exhibits high specific surface area, enabling the absorbent to reach the equilibrium absorption capacity within 5 minutes. In addition, magnetic nanoparticles (MNPs) are incorporated into each fiber to facilitate the recovery process without significant reduction in the absorption capacity. We envision that these absorbents offer a promising route for the quick and thorough clean-up of spilled oil due to their high absorption capacity, fast absorption rate, and ease of recovery. |
