Abstract

Herein, superhydrophilic polyester textiles were fabricated via plasma modification with a view to their application in the separation of oil–water mixtures. The research delved into the impact of fabric treatment and variations in grammage, including 77, 104, and 132 g/m² on separation performance and flux. The surface characteristics of the prepared polyester textiles were assessed through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses. Additionally, the antifouling properties and reusability of both fabrics without treatment and treated fabrics were examined. Notably, employing a five-layer treated fabric substantially improved separation efficiency up to 99.78%, and even after 5 cycles, it remained at 91.80%, attributable to the enhanced hydrophilicity conferred by APP treatment. In addition, after 20 abrasion cycles, the oil contact angle (OCA) of the five-layer treated polyester fabric decreased by 36 °.

利用不含任何添加剂的气压等离子体对聚酯织物进行表面改性，以提高油水分离效率

本文通过等离子体改性制造了超亲水性聚酯纺织品，以期将其应用于油水混合物的分离。研究深入探讨了织物处理和克重变化（包括 77、104 和 132 克/平方米）对分离性能和通量的影响。通过扫描电子显微镜（SEM）和能量色散 X 射线光谱（EDS）分析评估了制备的聚酯纺织品的表面特性。此外，还考察了未经处理的织物和处理过的织物的防污性能和可重复使用性。值得注意的是，采用五层处理的织物大大提高了分离效率，最高可达 99.78%，即使在 5 次循环后，分离效率仍保持在 91.80%，这归因于 APP 处理增强了亲水性。此外，经过 20 次磨损后，五层处理聚酯织物的油接触角（OCA）下降了 36°。
