Abstract Hydrophobic modified cotton filter fabric is a key material in the chemical industry, as it is used in common industrial filtration and precision separation processes. Most studies have focused on improving the hydrophobicity of cotton filter fabric. However, the hydrophobic durability, which is the most critical factor that determines the application scope of the material, remains unaddressed. Herein, we report that CS2 activation and subsequent 1-octadecene graft copolymerization via ARGET-ATRP of the cotton filter fabric leads to a modified material that is largely superior to the traditional cotton filter fabric. The modified cotton filter fabric exhibits high hydrophobicity, with an initial water contact angle of 141.0° and excellent hydrophobic durability, as demonstrated by the residual water contact angle of 126.7° after a 150 min droplet holding time. Moreover, the modified hydrophobic sample fabric was resistant to a variety of physical stresses and chemicals, maintaining its hydrophobic properties following multiple resistance tests, such as immersion in oily water for 10 days, immersion in organic solvents for 72 h, or when subjected to UV radiation for 24 h.

CS2/NaOH活化对ARGET-ATRP改性棉滤布疏水耐久性的影响

摘要 疏水改性棉滤布是化工行业的关键材料，用于普通工业过滤和精密分离过程。大多数研究都集中在提高棉滤布的疏水性上。然而，疏水耐久性是决定材料应用范围的最关键因素，仍未得到解决。在此，我们报告了 CS2 活化和随后通过棉滤织物的 ARGET-ATRP 进行的 1-十八烯接枝共聚导致改性材料，该材料在很大程度上优于传统的棉滤织物。改性棉滤布具有高疏水性，初始水接触角为 141.0°，疏水耐久性优异，残留水接触角为 126。150 分钟液滴保持时间后 7°。此外，改性疏水样品织物能够抵抗各种物理应力和化学物质，在多次抵抗测试后保持其疏水性，例如在油水中浸泡 10 天，在有机溶剂中浸泡 72 小时，或在受到紫外线照射时辐射 24 小时。
