Abstract
The discharge of wastewater containing oil and dye has caused serious water pollution, and it is difficult to achieve simultaneous oil-water separation and dye degradation with a single material. Herein, two multifunctional fabrics were prepared from different steps during one preparation process for the first time, as to the best of our knowledge, by simple chemical oxidation polymerization and dipping. Ag nanoparticles were introduced by reduction of polypyrrole (PPy) after the in-situ deposition of PPy on cotton (namely, CF-PPy/Ag). Then, CF-PPy/Ag was immersed in the polydimethylsiloxane (PDMS) solution to achieve wettability modification (namely, PDMS@CF-PPy/Ag). PDMS@CF-PPy/Ag not only showed good durability and superhydrophobicity, but also own excellent antibacterial property (>99.99 %) against E. coli and S. aureus. The fabric exhibited excellent oil-water separation performance and recyclability, with a high separation efficiency (>98.5 %) after 50 cycles. Meanwhile, CF-PPy/Ag could be applied for dye degradation due to the excellent antibacterial and photocatalytic activity. The degradation efficiencies of CF-PPy/Ag for methyl blue and methyl orange were 90.1 % and 95.2 %, respectively, after 90 min of simulated sunlight irradiation. More importantly, we further designed a simple device that combined both CF-PPy/Ag and PDMS@CF-PPy/Ag, which could simultaneously achieve efficient oil-water separation and dye degradation. Therefore, we believe that the efficient strategy of combining multifunctional cotton fabrics derived from different steps during one preparation process for multi-purpose purification of water can provide a promising solution for the treatment of complex water pollution and a new idea for the collaborative application of multifunctional fabrics in the field of oil-water separation.
