Professor Jiang Lei of the Institute of Chemistry of the Chinese Academy of Sciences and Professor Feng Lin of Tsinghua University have invented a system that can separate water from an oil-water mixture. This is very important for the cleanliness of our environment and energy recovery in the future. The leakage of oil on the seabed has caused no small trouble to our environment and economy. Cleaning up oil is not an easy task. Many researchers are trying to find a good way to separate oil and water, not only to protect our environment, but also to recover as much as possible the scarce resource of oil. Most of the currently reported methods focus on separating oil from water. In this process, due to the lipophilic nature of the oil-absorbing material, oil stains tend to adhere to the surface and pores of the material, which is very difficult to remove, making the separation method less effective and recycling oil and materials. Professor Jiang Lei of the Institute of Chemistry of the Chinese Academy of Sciences and Professor Feng Lin of Tsinghua University have invented a new system for separating oil and water. Unlike previous methods, they adopted the idea of ​​separating water from oil. They prepared a polyacrylamide hydrogel layer on the stainless steel mesh, making this grid have both superhydrophilic and underwater superoleophobic properties. Such a material with special wetting properties acts as a filter layer, which not only allows water to leak through, but also blocks oil. Experiments show that this method can recover more than 99% of the oil from the oil-water mixture. And it is not only suitable for crude oil, but also effective for other cracked products such as diesel, gasoline, n-hexane and petroleum ether. This method does not require external energy, and the oleophobic properties make the filter layer not easily contaminated by oil, easy to clean and recycle, and extend the service life. This filter system is very important for the cleanliness of the future environment and energy recovery.
