For the actual courses of surroundings conservation, segregation of oily water mixtures is increasingly desired. The hydrophobic/oleophilic cotton fabric as a system for removing oil from a water phase was prepared by reversible addition fragmentation chain transfer (RAFT) reaction technology. A piece of fabric was modified with the RAFT chain transfer agent S-1-Dodecyl-S′-(α′,α″-dimethyl-α″-acetic acid) trithiocarbonate (CTA), then hydrophobic/oleophilic interface was fabricated on the CTA modified fabric by grafting the octadecyl methacrylate. The chemical structures, surface topographies and surface properties were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and contact angle experiments, respectively. The ability of as-prepared fabric with a separation efficiency was better than 97.0 % on average for various types of oil/water mixtures demonstrated the hydrophobic/oleophilic property. We believe that the work will extend the applications of fabric in the oil/water separation and provide a new design in practical applications.

对于环境保护的实际过程，越来越需要油水混合物的分离。通过可逆加成断裂链转移（RAFT）反应技术制备疏水/亲油棉织物作为水相脱油系统。用RAFT链转移剂S-1-十二烷基-S'-(α',α"-二甲基-α"-乙酸)三硫代碳酸酯(CTA)对一块织物进行改性，然后在织物上制备疏水/亲油界面。通过接枝甲基丙烯酸十八烷基酯的 CTA 改性织物。化学结构、表面形貌和表面性质分别通过傅里叶变换红外光谱 (FTIR)、扫描电子显微镜 (SEM) 和接触角实验进行表征。所制备织物的分离效率优于97。对于各种类型的油/水混合物，平均为 0 % 表现出疏水/亲油特性。我们相信这项工作将扩展织物在油水分离中的应用，并在实际应用中提供一种新的设计。
