Abstract:
Frequent oil spills cause substantial economic losses and pose a significant threat to human life. Urgent measures must be taken to develop a highly effective approach to mitigating oil spills and minimizing their potential consequences. Herein, we synthesized MS@COFs-F, fluorinated covalent organic framework-decorated superhydrophobic sponges, to clean up crude oil spills efficiently. The synthesis method involved a simple and effective room-temperature approach, utilizing 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (TAPT) as the amine monomer and binding it with three aldehyde monomers of varying fluoride content. The MS@COFs-F with the highest fluorine content, known as MS@COFs-F4, exhibited low surface energy, superhydrophobicity (water contact angle of 155.7 degrees), a large specific surface area of 180 m(2)/g, and exceptional chemical, mechanical, and thermal stability. MS@COFs-F4 demonstrated remarkable effectiveness in adsorbing crude oils and organic solvents of diverse viscosities, exhibiting an adsorption capacity between 68.5 and 125.9 g/g, achieving an oil-water separation efficiency exceeding 97.0 %. Additionally, MS@COFs-F4 showcased self-cleaning and flame-retardant properties, further enhancing its suitability for real-world applications. MS@COFs-F4 holds the potential to offer a novel, safe, and effective approach in addressing oil spill incidents.
