| titleOfInvention | Superhydrophilic and superoleophobic oil-water separation membrane with humidity responsiveness as well as preparation method and application of oil-water separation membrane |
| abstract | The invention belongs to the technical field of preparation of oil-water separation membranes and discloses a superhydrophilic and superoleophobic oil-water separation membrane with humidity responsiveness as well as a preparation method and an application of the oil-water separation membrane in oily sewage treatment and oil-water separation. The oil-water separation membrane is prepared with the method comprising the following steps: inorganic nanoparticles are prepared, subjected to oleophobic modification through a perfluoroalkyl siloxane solution and mixed with a prepared hydrophilic coating, and a hybrid hydrophilic coating is obtained; a silk screen is coated with a UV cured water-based anticorrosive coating with a dip coating or spray coating method, and an anticorrosive base coat membrane is obtained; the anticorrosive base coat membrane is coated with the hybrid hydrophilic coating with the dip coating or spray coating method, dried and cured, a micro-nano coarse structure is constructed, and the superhydrophilic and superoleophobic oil-water separation membrane with humidity responsiveness is obtained. The separation membrane has an initial contact angle with water in air being 150 degrees, the angle is reduced to 0 degree within 10-30 min, and the separation membrane has a contact angle with oil drops either in air or underwater being larger than 150 degrees all along. |
