Fiber-based sorbent materials are an essential part of containing oil spills, thus preventing ecological damage. Poly(styrene--isobutylene--styrene) thermoplastic elastomer fibers were successfully produced by centrifugal spinning. Scanning electron microscopy revealed that the fibers were bead free and smooth-surfaced, with an average fiber diameter of 5.9 ± 2.3 μm. Contact angle measurements proved the highly hydrophobic (water contact angle of 126.8 ± 6.4°) and highly oleophilic nature of the fiber mat. The sorption and retention capacities of the fiber mat were tested for various oils and benchmarked against polypropylene as the industry standard and polystyrene, which is widely used in the literature. The oil uptake of the fiber mat showed a strong correlation with the viscosity of the oil, resulting in sorption capacities of 10.1 ± 0.8 g/g for sunflower oil, 19.9 ± 2.1 g/g for motor oil, and 23.8 ± 1.8 g/g for gear oil. Oil-water separation tests were also conducted, resulting in ~100% oil removal. The thermoplastic elastomer fiber mat outperformed the industry standard; however, the polystyrene fiber mat demonstrated the best oil sorption performance.
基于纤维的吸附材料是控制石油泄漏从而防止生态破坏的重要组成部分。通过离心纺丝成功制备了聚（苯乙烯-异丁烯-苯乙烯）热塑性弹性体纤维。扫描电子显微镜显示，纤维无珠粒且表面光滑，平均纤维直径为5.9±2.3μm。接触角测量证明纤维毡具有高度疏水性（水接触角为126.8±6.4°）和高度亲油性。测试了纤维毡对各种油的吸附和保留能力，并与作为行业标准的聚丙烯以及文献中广泛使用的聚苯乙烯进行了对比。纤维毡的吸油率与油的粘度有很强的相关性，向日葵油的吸附容量为10.1±0.8 g/g，机油为19.9±2.1 g/g，齿轮油为23.8±1.8 g/g。还进行了油水分离测试，油去除率约为100%。热塑性弹性体纤维毡的性能优于行业标准；然而，聚苯乙烯纤维毡表现出最佳的吸油性能。
