A review of superwetting aerogel-based oil-water separation materials

With the acceleration of the industrial process and the improvement of people's living standards, a large amount of oily wastewater has been produced, which has threatened the ecological system and human health. Therefore, the treatment of oily wastewater has become a problem and challenge to be solved. Benefit from its excellent three-dimensional porous structure, aerogels are widely used in the sphere of oil-water separation. This paper mainly introduces superwetting aerogel-based oil-water separation materials. Elaborate on its separation mechanism and acquisition pathway. The performance and advantages of polymer-based aerogels, biomass-based aerogels, inorganic-based aerogels and carbon-based aerogels in oil-water separation are analyzed and summarized. Finally, the application prospect of aerogel-based materials in the field of oil-water separation was prospected.
