Adsorbents are widely used as a method to remove oil spills from the ocean. However, secondary contamination occurs because polymer adsorbents are difficult to collect and dispose after use. In this research, magnetic nanoparticles embedded biodegradable polycaprolactone mats (PCL/MNP) were prepared via facile one-step electrospinning method. Compared with pure PCL mat, PCL/MNP mat had high oil adsorption capacity (pure PCL 21.79 g/g, PCL/MNP 0.5 20.46 g/g of Diesel), increased hydrophobicity (WCA, 146.5°), and magnetic response (magnetization, 7.7 emu/g) in aqueous phase was evaluated despite the addition of MNP. Therefore, after adsorbing oil, it can be easily removed by an external magnetic field, and even if lost, it is decomposed without environmental pollution due to biodegradability. Thus, our research gives insight into the design of oil spill sorbents as oil spill control in complex environments. |
