Photothermal conversion-assisted oil Water separation by superhydrophobic Cotton yarn prepared via the silver mirror reaction

Solar-driven pH-responsive oil–water separation membranes for effective oil–water emulsion separation

“…Li et al 21 demonstrated a simple method for preparing environmentally benign multifunctional membranes for oil-water separation and desalination by the in situ regeneration of lignocellulose; the multifunctional membrane has excellent separation efficiency (99.90%) for oil-in-water emulsions, and the evaporation rate was 1.39 kg m À2 h À1 . By using a surface-modification method, Wang et al 22 prepared a novel type of super hydrophobic cotton yarn (CF-Ag-NDM), which exhibited super hydrophobicity and photothermal conversion characteristics; after 2 min of exposure to sunlight, the surface temperature of CF-Ag-NDM rapidly increased to 70 1C and achieved an oil-water separation efficiency of 98%.…”

A Composite Fabric with Dual Functions for High-Performance Water Purification

“…The bifunctional fabric is fabricated by depositing titanium dioxide@carbon black nanoparticles onto the cotton fabric (TiO 2 @CB/CF, Figure 1 ). The TiO 2 @CB/CF enables synergistic effects of solar-driven evaporation and photocatalysis: due to the fast water transport of hydrophilic cotton fabric [ 40 , 41 , 42 ] and the photothermal effect of CB, the TiO 2 @CB/CF can generate clean water through localized heating on the air–water interface; with sunlight irradiation, the photocatalytic function of the TiO 2 @CB/CF can degrade the contaminants of sewage, and it is worth noting that the photothermal effect of CB can accelerate the photocatalytic effect of TiO 2 . The resulting bifunctional fabric can achieve an outstanding water evaporation rate of 1.42 kg m −2 h −1 and a conversion efficiency of 90.4% in MB solution under one-sun irradiation.…”

Effect of silylating agents on the superhydrophobic and self-cleaning properties of siloxane/polydimethylsiloxane nanocomposite coatings on cellulosic fabric filters for oil–water separation

“…Recent trends in human activities have led to frequent oil spills and waste disposals, and these have severely impacted on marine lives. 1 Discharges from industrial wastewaters generate oil-based environmental eluents (e.g., toluene) and watersoluble pollutants (e.g., dyes) whose dispersion within the food chain are also detrimental to human health. 2 In cases of oil spills, the formation of organic lms isolates the seawater from rapid oxygen exchange with the surrounding atmosphere while starving marine lives of the needed molecular oxygen sustenance.…”
