PDMS-based materials have been extensively studied in oil-water separation. However, their successful application is commonly limited by low efficiency, vulnerability to acid/alkali, complex processing procedures, incapability for emulsion separation, etc. Here, a highly durable and robust separation material developed coating copolymers on cotton textiles with facile sol-gel approach. Solely driven gravity, this new not only can enable effective of mixture flux as high ∼7500 L m-2 h-1 but also separate surfactant-stabilized water-in-oil emulsion. Moreover, it remains fully functional even the environments concentrations acid, alkali, or salt. This novel versatile strategy holds great promise be widely used practical applications including oil/chemical spill accidents industrial sewage emission.
