Water scarcity and pollution has become one of the most serious problems in the world. Generally, both oils and microorganisms exist in polluted water, hence multi-functional materials for the removal of diverse substances from water are desired. We reported a facile method for preparing cotton fabric possessing hybrid poly(sodium methacrylate) (pNaMAA)/silver nanoparticles (AgNPs) for oil/water separation and water disinfection. A crosslinked pNaMAA layer was generated on the cotton surface by ultraviolet-initiated polymerization. By replacing Na+in pNaMAA molecules, Ag+was incorporated into the fabric and then was reduced to AgNPs in situ by photo-thermal reduction. Due to the high underwater oleophobicity and bactericidal effect of the pNaMAA/AgNP hybrid layer, the gravity-driven oil/water separation efficiency of the prepared fabric was higher than 99% and the bacteria killing ratio achieved nearly 100%. Furthermore, AgNPs exhibited relatively good fastness during application. Combining their excellent oil removal and water disinfection effectiveness, these textile-based materials provide a promising future in the field of point-of-use water purification.
