A hierarchically porous sponge for stabilized emulsion separation with high filtration flux and separation efficiency

Abstract

Emulsion separation remains a challenge in oil-water separation field, because it is extremely stable in the liquid medium. The main difficulty is that the filtration flux and separation efficiency are...

Recent advances in superwetting materials for separation of oil/water mixtures

“…11c. Other stimulations for the surface wetting transition for oil/water separation include UV, 117 temperature, 118,119 pH, 120 pore size, 121 and wettability, 122 which are listed in Table 5. Notably, the design and fabrication of superwetting materials are usually complicated with a high cost, which requires substantial further endeavours.…”

An environment friendly multifunctional ZnO/wood fiber composite for the treatment of wastewater mixed with emulsions and dye

“…The materials used for emulsion separation include sponges, 4 membranes, 5 and aerogels, 6 among others. However, these materials entail sophisticated operational procedures, including pretreatment and breaking the emulsion.…”

A dual-functional superhydrophobic PDMS@ZnO@MS sponge for highly efficient oil–water separation and photocatalytic degradation

“…[12][13][14] However, the design and development of functionalized adsorbent materials used in oil-water separation is still a challenge. Various functional materials such as cellulose, 15 graphite, 16 cotton fabrics 17 and sponge 18 have been used widely to separate oil from water. Among them, the three-dimensional (3D) porous sponge has attracted significant attention in the field of oil/water separation owing to its welldeveloped pore structure and large surface area.…”
