| titleOfInvention | NH2-MIL-125/POD-COOH ultrathin homogeneous hybrid forward osmosis membrane and preparation method thereof |
| abstract | The invention provides a preparation method of an NH2-MIL-125/POD-COOH ultrathin homogeneous hybrid forward osmosis membrane, belonging to the technical field of high polymer materials. The invention firstly prepares the MOFs material (NH) 2 MIL-125), Polyoxadiazole (POD) material and carboxyl-containing polyoxadiazole (POD-COOH) material, and further performing molecular design on NH 2 the-MIL-125 material is introduced into the molecular structure of the carboxyl-containing polyoxadiazole material through the chemical bond effect, and the series of NH is successfully prepared 2 The MIL-125/POD-COOH hybrid forward osmosis membrane material is shown in figure 1, and then the ultrathin homogeneous hybrid forward osmosis membrane is prepared by a solution casting method by using the material. Finally provides a preparation method of the NH2-MIL-125/POD-COOH hybridized forward osmosis membrane. Because the forward osmosis membrane does not have a supporting layer, the phenomenon of internal concentration polarization in the forward osmosis separation operation process can be eliminated, and the forward osmosis water treatment efficiency is greatly improved. In addition, the introduction of porous hydrophilic MOFs materials with high sieving efficiency for water and salt enhances the water permeation and desalination performance of the hybrid membrane during forward osmosis separation operations. In conclusion, the material has wide application prospect in the fields of seawater desalination, brackish water treatment and the like. |
