Ecosystems suffer from increased oil exploitation and frequent oil spills, which calls for effective, environment-friendly, and economically viable solutions. To address this, abandoned gunny sacks as the concerned jute fabric were superhydrophobically (water contact angle ∼159°) modified, incorporating titanium dioxide (TiO) nanoparticles and hexadecyltrimethoxysilane (HDTMS), rendering a facile drop casting procedure. The modified superhydrophobic-superoleophilic jute fabric has been identified as a high-performance filter with superior reusability that can separate oil-water mixtures in challenging environmental conditions (including potent acidic, alkaline, highly saline, aqueous, frigid, and blistering water environments) while maintaining high separation efficiency. In continuation, static conditions indulging a batch and continuous oil separation performance and dynamic conditions stimulating turbulence in the oil-water mixture were proficiently carried out, mimicking real-world circumstances. As a result, the modified jute fabric has the advantages of high separation efficiency, stable recyclable properties, and outstanding durability, highlighting its enormous potential for use in practical applications.
生态系统因石油开采增加和频繁的石油泄漏而受损，这就需要有效、环保且经济可行的解决方案。为解决这一问题，将废弃麻袋这种相关的黄麻织物进行超疏水改性（水接触角约为159°），加入二氧化钛（TiO）纳米颗粒和十六烷基三甲氧基硅烷（HDTMS），采用简便的滴铸工艺。改性后的超疏水超亲油黄麻织物被认定为一种具有卓越可重复使用性的高性能过滤器，它能在具有挑战性的环境条件下（包括强酸性、碱性、高盐度、水性、寒冷和滚烫的水环境）分离油水混合物，同时保持高分离效率。接着，分别在静态条件下进行批量和连续的油分离性能测试，以及在动态条件下模拟油水混合物中的湍流，以模拟实际情况。结果表明，改性黄麻织物具有分离效率高、可稳定回收和耐久性优异的优点，凸显了其在实际应用中的巨大潜力。
