全球环境挑战包括对能够有效清除水中溢油的新兴材料的需求。具有高吸附能力和优异油水分离性能的吸附剂材料的制造和升级已成为当今备受关注的话题。本文首次通过连续静电纺丝将具有疏水亲油表面的三维互连多孔聚苯乙烯纤维组装在一起，呈现出优越的溢油清理性能。本研究中应用的关键创新点是在这些分层纤维之间产生梯度结构系统，可以形成梯度纤维间空隙，从而在油的吸附过程中产生梯度毛细作用力。所设计的超吸附剂材料对各种油类具有高的吸附能力和超快的吸附速率。该吸油剂对泵油、菜籽油和柴油的初始吸油量分别为307.24 g g−1、224.31 g g−1和84.52 g g−1，均优于其他普通纤维型吸油剂。此外，设计的材料，支持在非织造布基材上，表现出从水中去除乳化油的出色性能。更重要的是，这种优越的材料可以应用于工业生产，因为它的低成本和简单的制造过程。本研究提出了一种制备高效吸油剂的简便方法，为工程吸油材料的升级换代提供了一种新的手段。
The global environmental challenge includes calls for emerging materials that can effectively clean up oil spillage from water. The fabrication and upgrading of sorbent materials with a high sorption capacity and excellent oil/water separation performance has become a high-profile topic today. Herein, for the first time, such a material is presented by assembling three-dimensional interconnected porous polystyrene fibers with a hydrophobic and oleophilic surface via successive electrospinning, showing superior performance in oil spillage cleanup. The key innovation point applied in this study is to produce a gradient structured system between these hierarchical fibres that can form gradient inter-fiber voids, resulting in a gradient capillary action force in the sorption process for oils. The as-designed super sorbent material exhibits high sorption capacity, as well as ultrafast sorption rates for various oils. The initial oil sorption amounts of the super sorbent material for pump oil, colza oil and diesel oil were approximated to 307.24 g g−1, 224.31 g g−1, and 84.52 g g−1, respectively, which are superior to those of other normal fibrous sorbents. Furthermore, the as-designed material, supported on a nonwoven fabric substrate exhibits outstanding performance for removing emulsified oil from water. More importantly, this superior material could be applied in industrial production because of its low cost and simple fabrication procedure. This study presents a facile strategy for the fabrication of efficient oil sorbents, providing a novel means for the upgrading of engineered sorption materials.
