Abstract

The increasing contamination of water resources by oily wastewater and human activities necessitates the development of efficient strategies for the remediation of polluted water sources. Due to the diversity of pollution sources, such as industrial wastewater, organic dyes, bacteria, and other complex pollutants, it is meaningful to develop a material capable of simultaneously treating these pollutants. The hydrophobic melamine sponge (PDMS@F-MOF@MS) was prepared using a simple impregnation method using zirconium metal-organic framework (UiO-66-NH₂), 1H,1H,2H,2H-perfluorodecyl trichlorosilane (FDTS), and polydimethylsiloxane (PDMS). The obtained PDMS@F-MOF@MS demonstrates remarkable superhydrophobic with a water contact angle of up to 156°. In addition, the PDMS@F-MOF@MS has robust adsorption capacity for a variety of organic solvents/oils (capable of absorbing 14.44 to 41.83 times its weight), a separation efficiency rate surpassing 95.9 %, and the ability to effectively separate oil-in-water emulsions. Furthermore, PDMS@F-MOF@MS demonstrates good mechanical properties and chemical stability, as well as good antibacterial and photocatalytic degradation properties. This project offers a valuable guide for the creation of versatile oil-water separation materials that can separate oil and water in variety of oily wastewater.

多功能超疏水PDMS@F-MOF@MS海绵：高效油水分离，抗菌活性，光催化性能

含油废水和人类活动对水资源的污染日益严重，需要制定有效的策略来修复受污染的水源。由于污染源的多样性，如工业废水、有机染料、细菌和其他复杂的污染物，开发一种能够同时处理这些污染物的材料是有意义的。以金属锆-有机骨架（uyo -66- nh2）、1H、1H、2H、2H-全氟癸基三氯硅烷（FDTS）和聚二甲基硅氧烷（PDMS）为原料，采用简单浸渍法制备了疏水性三聚氰胺海绵（PDMS@F-MOF@MS）。所得PDMS@F-MOF@MS具有优异的超疏水性，其水接触角可达156°。此外，PDMS@F-MOF@MS对多种有机溶剂/油具有较强的吸附能力（可吸附其质量的14.44 ~ 41.83倍），分离效率超过95.9%，并能有效分离水包油乳状液。此外，PDMS@F-MOF@MS具有良好的力学性能和化学稳定性，以及良好的抗菌和光催化降解性能。该项目为研制能够分离各种含油废水中的油水的多功能油水分离材料提供了有价值的指导。

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
