英文摘要

Oil/water separation is an important field aiming to resolve industrial oily wastewater and oil-spill pollution, as well as environmental protection. However, the separation of oil-water mixtures, especially surfactant-stabilized oil-water emulsions, is a worldwide challenge. To this end, we developed a versatile and efficient approach to separate various highly stable emulsions including both surfactant-stabilized W/O emulsions and O/W emulsions with high separation efficiency using nanoporous divinylbenzene (DVB)/SiO2 hybrid material. The highly effective separation property of the hybrid material is attributed to its superhydrophobicity, high specific surface area and nanopore size distribution. Therefore, the versatile emulsion separation of hybrid material shows obvious advantage over most superwetting surfaces that only have effect on free oil-water mixtures or one form emulsion (W/O emulsions or O/W emulsions). Besides, the as-prepared hybrid material can rapidly swell various organic solvents from water selectively with high absorption capacity because of the present multi-level nanopores which can enhance adsorption performance for their improved accessibility and high surface area. Moreover, the hierarchical nanoporous structure of hybrid material still remained even after repeated separation procedures indicating the outstanding fouling resistance and good reusability.
