通过静电纺丝工艺制备了一种由聚氯乙烯（PVC）/聚苯乙烯（PS）纤维组成的新型高容量吸油剂。研究了PVC/PS吸附剂的吸附容量、油/水选择性和吸附机理。结果表明，PVC/PS吸附剂对机油、花生油、柴油和乙二醇的吸附容量分别为146、119、38和81 g/g。它大约是商用聚丙烯 (PP) 吸附剂的 5-9 倍。 PVC/PS吸附剂还具有优异的油/水选择性（约1000倍）和高浮力，清除水中的油污。 SEM分析表明纤维之间的空隙是高容量的关键。电纺 PVC/PS 吸附剂是广泛使用的用于溢油清理的 PP 吸附剂的更好替代品。
A novel, high-capacity oil sorbent consisting of polyvinyl chloride (PVC)/polystyrene (PS) fiber was prepared by an electrospinning process. The sorption capacity, oil/water selectivity, and sorption mechanism of the PVC/PS sorbent were studied. The results showed that the sorption capacities of the PVC/PS sorbent for motor oil, peanut oil, diesel, and ethylene glycol were 146, 119, 38, and 81 g/g, respectively. It was about 5-9 times that of a commercial polypropylene (PP) sorbent. The PVC/PS sorbent also had excellent oil/water selectivity (about 1000 times) and high buoyancy in the cleanup of oil over water. The SEM analysis indicated that voids among fibers were the key for the high capacity. The electrospun PVC/PS sorbent is a better alternative to the widely used PP sorbent for oil spill cleanup.
