A mechanically robust and high-capacity oil sorbent is prepared by electrospinning a blend of polystyrene (PS) and polyacrylonitrile (PAN). The morphology, oil sorption capacity and mechanical property of the fibers formed in different compositions are investigated in detail. It is shown that the oil sorption capacity is a result of both the chemical composition and the specific surface area which related to diameter size. The addition of PAN as a component in fibrous sorbents can significantly improve the mechanical properties of PS fibers. Moreover, the oil sorption capacity increases with decreasing fiber diameter. The results also show that the maximum sorption capacities of the PS/PAN sorbent for pump oil, peanut oil, diesel, and gasoline were 194.85, 131.70, 66.75, and 43.38 g g(-1), respectively. Additionally, the sorbent exhibits quick oil sorption speed as well as high buoyancy, which make it a promising candidate for use as an oil spill cleanup sorbent.
通过静电纺丝聚苯乙烯（PS）和聚丙烯腈（PAN）的混合物制备了一种机械性能强且高容量的吸油剂。详细研究了不同组成下形成的纤维的形态、吸油能力和机械性能。结果表明，吸油能力是化学成分和与直径大小相关的比表面积共同作用的结果。在纤维状吸附剂中添加PAN作为一种成分可以显著提高PS纤维的机械性能。此外，吸油能力随纤维直径的减小而增加。结果还表明，PS/PAN吸附剂对泵油、花生油、柴油和汽油的最大吸附容量分别为194.85、131.70、66.75和43.38 g g(-1)。此外，该吸附剂具有快速的吸油速度以及高浮力，这使其成为用作溢油清理吸附剂的有前途的候选材料。
