Magnesium stearate-coated superhydrophobic sponge for oil/water separation: Synthesis, properties, application

Facile Preparation of Robust Superhydrophobic/Superoleophilic TiO2-Decorated Polyvinyl Alcohol Sponge for Efficient Oil/Water Separation

“…Similarly, Parsaie et al found that the contact angle of the superhydrophobic polyurethane (PU) sponge does not show obvious changes after 10 cycles of abrasion tests. 2 You et al reported that chitosan–PVA–TiO 2 -coated copper mesh still maintains its superhydrophobicity after 25 cycles of abrasion tests. 17 Furthermore, ultrasonification is also used to evaluate the durability of the TiO 2 –PVA sponge in ethanol for different times (i.e., 0–60 min).…”

“… 1 The toxic chemicals in oily wastewater seriously threaten the survival of aquatic organisms, and some toxic substances enter the human body through the food chain and significantly influence human health. 2 To mitigate the threat of oily wastewater, traditional approaches have been utilized to purify oily wastewater, including controlled burning, air flotation, chemical dispersion, and bioremediation. 3 , 4 However, these methods suffer from secondary pollution, high cost, and low efficiency.…”

“…Modern industries and frequent oil spill incidents have produced a large quantities of oily wastewater, which causes serious pollution in the environment . The toxic chemicals in oily wastewater seriously threaten the survival of aquatic organisms, and some toxic substances enter the human body through the food chain and significantly influence human health . To mitigate the threat of oily wastewater, traditional approaches have been utilized to purify oily wastewater, including controlled burning, air flotation, chemical dispersion, and bioremediation. , However, these methods suffer from secondary pollution, high cost, and low efficiency. , Thus, it is necessary to develop low-cost, environmentally friendly, stable, and efficient approaches or materials for the treatment of oily wastewater.…”

Durable superhydrophobic Fe3O4@C/PVDF/PU sponge for efficient separation of surfactant-stabilized organic solvent/water emulsions

“…With the rapid development of offshore oil exploitation, transportation and chemical industry, the industrial oily wastewater and chemical leakage incidents have posed non-negligible threatens to the marine environment and ecological balance. 1,2 In recent years, oil/water emulsions, especially surfactant-stabilized oil/water emulsions, have been widely used in the progress of industrialization, but they also bring many negative effects such as the hazard to human health, chemical corrosion, water resources and air pollutions. 3 Compared with immiscible oil/water mixtures, there are great challenges for the separation of surfactant-stabilized emulsions because the addition of surfactants enhances the kinetic and thermodynamic stabilities of the dispersed phase in the continuous phase.…”

Preparation and modification of cellulose sponge and application of oil/water separation

“…Increasing industrial oily wastewater and frequent oil leakage accidents have caused serious harm to the ecological environment. [1][2][3][4] Therefore, the research and development of effective, convenient, and low-cost oil/water separation materials has attracted extensive attention worldwide.…”
