Versatile superhydrophobic PDMS@F-MOF@MS Sponge: Efficient oil-water separation, antimicrobial activity, and photocatalytic performance
The increasing contamination of water resources by oily wastewater and human activities necessitates the development of efficient strategies for the remediation of polluted water sources. Due to the diversity of pollution sources, such as industrial wastewater, organic dyes, bacteria, and other complex pollutants, it is meaningful to develop a material capable of simultaneously treating these pollutants. The hydrophobic melamine sponge (PDMS@F-MOF@MS) was prepared using a simple impregnation method using zirconium metal-organic framework (UiO-66-NH 2 ), 1H,1H,2H,2H-perfluorodecyl trichlorosilane (FDTS), and polydimethylsiloxane (PDMS). The obtained PDMS@F-MOF@MS demonstrates remarkable superhydrophobic with a water contact angle of up to 156°. In addition, the PDMS@F-MOF@MS has robust adsorption capacity for a variety of organic solvents/oils (capable of absorbing 14.44 to 41.83 times its weight), a separation efficiency rate surpassing 95.9 %, and the ability to effectively separate oil-in-water emulsions. Furthermore, PDMS@F-MOF@MS demonstrates good mechanical properties and chemical stability, as well as good antibacterial and photocatalytic degradation properties. This project offers a valuable guide for the creation of versatile oil-water separation materials that can separate oil and water in variety of oily wastewater.
