Soil-coated fabrics were fabricated by scrape-coating of soil slurry onto cotton fabrics. The raw materials, soil, and cotton fabrics were, respectively, obtained from farmland and waste bed sheets, making the method a zero-material cost way to produce superwetting membrane. The superhydrophilic/underwater superoleophobic soil-coated fabrics exhibit high efficiency (>99%), ultra-high flux (~45,000 L m h), and excellent antifouling behavior for separating water from various oils driven by gravity. The simple fabrication and superior performance suggest that the soil-coated fabric could be a promising candidate as a filtration membrane for practical applications in industrial oily wastewater and oil spill treatments.
通过将土壤浆液刮涂到棉织物上制备了涂有土壤的织物。原材料土壤和棉织物分别取自农田和废旧床单，使得该方法成为一种零材料成本生产超湿膜的方式。超亲水/水下超疏油的涂有土壤的织物在重力驱动下从各种油中分离水时表现出高效率（>99%）、超高通量（~45,000 L m⁻² h⁻¹）和优异的抗污性能。这种简单的制备方法和优异的性能表明，涂有土壤的织物有望成为用于工业含油废水和溢油处理实际应用的过滤膜材料。
