| Abstract |
In this work, a facile and economic strategy for the fabrication of hydrophobic fabric for the efficient oil-water separation was demonstrated. The hydrophobic fabric was prepared by an one-step hydrothermal method in the mixture of carbon soots and octadecyltrimethoxysilane (OTMS) in the presence of cotton fabric sheet. The surface morphology and chemical of the hydrophobic fabric were characterized by field-emission scanning electron microscopy, X-ray photoelectron spectroscopy and fourier-transform infrared spectroscopy. The water contact angle of the hydrophobic fabric is 136.6 ± 2.0° and exhibits an excellent self-cleaning performance. The hydrophobic filter shows high separation efficiencies (> 99%) for various oils with different viscosity and density such as hexane, toluene, octane, dichloroethane, chloroform and canola oil. During the 30 cycles of recycling, the water contact angle was maintained at 136.6° and the separation efficiency was more than 98 %. In addition, it showed an excellent performance in harsh environments such as highly acidic, alkaline, salty and hot solutions to deal with oil spills. |
