Ultra-hydrophobic cotton is used for oil and water separation

In a recently published study, researchers developed ultra-hydrophobic cotton using silicon dioxide nanoparticle treatment and then surface functionalization with methyl triclosane.
water pollution caused by oil spills has recently become an important issue in marine ecosystems. The use of oil/hydrophobic adsorbents for oil-water separation as an economical and environmentally friendly solution has attracted a lot

.
recently, scientists developed ultra-hydrophobic/ultra-oil-pro-oil cotton by treating silicon dioxide nanoparticles (-800 nanometers) and then using methyl triclosane (MTCS) for surface functionalization. X-ray diffraction, field emission scanning electron microscopy, energy dispersion X-ray spectroscopy and Fourier transform infrared spectroscopy studies have shown that the formation of false amorphous SiO 2 NPs and C-Si-O mulch overlays on cotton fibers makes it possible. Ultra-hydrophobic, increased surface roughness.
ultra-hydrophobic, with excellent absorption capacity
cotton treated by MTCS / SiO 2 in water - cotton and oil - cotton interface contact angle of 173±2 degrees and 0 degrees, respectively. In addition, MTCS/SiO2-treated cotton exhibits ultra-hydrophobicity throughout the pH range and has excellent absorption capacity for a wide range of oil-water mixtures, ranging in weight from about 30 to 40 times its weight.
