摘要：

As a natural substance, sand is abundant in deserts, but it has not been widely used due to its superhydrophilic.In this study, sand was used as the substrate and silver nanoparticles were assembled on its surface, after modification with octadecanethiol, the sand possess superhydrophobic-superhydrophilic properties (contact angle of water droplets was 160°, contact angle of oil droplets was 0°). The superhydrophobic properties of sand surface can not only selectively separate the light oil on water from the heavy oil under water, but also efficiently separate the emulsion formed by oil and water and realize water storage in desert environment.The related research is expected to provide a new idea for the preparation of sewage treatment materials and the prevention of land desertification. © 2022, Materials Review Magazine.
