Abstract
- Oily wastewater and organic dye wastewater discharged from modern industry have given rise to serious environmental pollution problem. Noticeably, the integration of superhydrophobicity and photocatalysis provides a facile and efficient way to address these issues. Inspired by mussel-chemistry, we fabricated a multifunctional paper through polydopamine (PDA)-induced in situ growth of Ag nanoparticles (Ag NPs) on paper surface followed by treatment with n-dodecyl mercaptan (n-DM). The resultant paper (PDA@Ag@n-DM) not only exhibited superhydrophobicity, but also displayed excellent antibacterial activity attributing to synergetic effect from bacterial adhesion resistance and photocatalytic bactericidal action. The PDA@Ag@n-DM paper showed good oil absorption capability, excellent separation properties for oil-water mixtures and water-in-oil emulsions, and obvious photocatalytic degradation ability for organic dye under visible light irradiation. Moreover, the PDA@Ag@n-DM paper presented enhanced mechanical, environmental and chemical stability. We believed that the as-prepared multifunctional paper will have great application promising in oily wastewater treatment and environmental remediation. [Display omitted] • A multifunctional paper was successfully fabricated by mussel-inspired chemistry. • The functional paper displayed superhydrophobicity with a WCA of 159.7°. • The functional paper had excellent antibacterial activity. • The functional paper exhibited excellent oil-water separation performance. • The functional paper showed good photocatalytic degradation of dye.
