Polymers provide a wide range of properties, and these properties can be greatly enhanced and modified through polymer blending. Polymer blending combines the properties and advantages of their original polymers. This paper showcases hydrophobic polymers prepared through polymer blending; these blends are characterized and evaluated for their efficiency in the removal of crude oil spills from aqueous media. The application of these blends holds a great deal of importance in preserving the environment and the recovery of lost oil in spills. The blends are produced using polystyrene (PS) as the matrix polymer and individually blending poly(vinyl chloride) (PVC) and polyethylene (PE) with the PS consisting of proportions of 5–20 wt.% each. The blends are then electrospun into bead-free microfibers with interconnected porosities as shown by their respective scanned electron micrographs. All fibrous sorbents showed a high affinity towards the removal of crude oil, motor oil, and diesel spills. The highly viscous motor spill showed a different pattern of sorption onto fibers than that of crude oil and diesel spills. Upon comparing all the studied electrospun fibers to commercially available polypropylene fibrous sorbents, results show that the sorption efficiency of the electrospun fibers is superior. Most notably, both PS-PE5 and PS-PVC5 fibers showed to be highly more effective than commercially available polypropylene (PP) sorbents towards all types of oil spills.

聚乙烯和聚氯乙烯共混聚苯乙烯纳米纤维吸附剂及其在清除各种溢油中的应用

聚合物提供了广泛的性能，通过聚合物共混可以大大增强和改性这些性能。聚合物共混结合了其原始聚合物的特性和优势。本文展示了通过聚合物共混制备的疏水性聚合物；对这些混合物进行了表征并评估了它们从水性介质中去除原油泄漏的效率。这些混合物的应用在保护环境和回收泄漏的石油方面具有重要意义。共混物是使用聚苯乙烯 (PS) 作为基体聚合物，并分别将聚氯乙烯 (PVC) 和聚乙烯 (PE) 与各占 5–20 wt.% 的 PS 共混而成。然后将共混物电纺成具有互连孔隙的无珠微纤维，如它们各自的扫描电子显微照片所示。所有纤维吸附剂都对去除原油、机油和柴油泄漏物表现出高亲和力。与原油和柴油泄漏相比，高粘度发动机泄漏显示出不同的纤维吸附模式。将所有研究的电纺纤维与市售聚丙烯纤维吸附剂进行比较，结果表明电纺纤维的吸附效率更高。最值得注意的是，PS-PE5 和 PS-PVC5 纤维在处理所有类型的漏油方面都比市售的聚丙烯 (PP) 吸附剂更有效。机油和柴油泄漏。与原油和柴油泄漏相比，高粘度发动机泄漏显示出不同的纤维吸附模式。将所有研究的电纺纤维与市售聚丙烯纤维吸附剂进行比较，结果表明电纺纤维的吸附效率更高。最值得注意的是，PS-PE5 和 PS-PVC5 纤维在处理所有类型的漏油方面都比市售的聚丙烯 (PP) 吸附剂更有效。机油和柴油泄漏。与原油和柴油泄漏相比，高粘度发动机泄漏显示出不同的纤维吸附模式。将所有研究的电纺纤维与市售聚丙烯纤维吸附剂进行比较，结果表明电纺纤维的吸附效率更高。最值得注意的是，PS-PE5 和 PS-PVC5 纤维在处理所有类型的漏油方面都比市售的聚丙烯 (PP) 吸附剂更有效。
