| titleOfInvention | UV cured super-hydrophilic and underwater super-oleophobic oil-water separation membrane, its preparation method and application thereof |
| abstract | The invention discloses a UV cured super-hydrophilic and underwater super-oleophobic oil-water separation membrane, its preparation method and an application thereof. The preparation method comprises the following steps: carrying out ultrasonic cleaning on a fabric silk screen; preparing nano sol by a sol-gel method, mixing 10-50 parts of a single-function UV cured oligomer, 60-80 parts of a bi-functional UV cured oligomer, 10-20 parts of multifunctional UV cured oligomer, 200-500 parts of silica sol, 1-5 parts of a waterborne photoinitiator and 1-5 parts of an emulsifier, and uniformly dispersing; coating a mixed liquor on the surface of a membrane by a dip-coating or spray process, drying, and carrying out UV curing to obtain a product. The surface of the oil-water separation membrane has a hydrophilic polymer molecular brush structure based on the micro-nano dual structure. The contact angle of the membrane to water and oil is 0 degree in the air, and the membrane has super-hydrophilicity. The contact angle of the membrane to oil drops is greater than 150 degrees underwater, and the membrane has low adherence to oil drops. The membrane provided by the invention can be used in separation of an oil-water mixture and treatment of oily sewage. |
