| titleOfInvention | A kind of thin layer composite forward osmosis membrane and preparation method thereof |
| abstract | The invention provides the preparation of a kind of thin layer composite forward osmosis membrane, the forward osmosis membrane of preparation, on the basis keeping original advantage, can effectively reduce interior concentration polarization, thus reach the target significantly improving water flux, and greatly can strengthen the combined strength bination of screen cloth supporting layer and interfacial polymerization cortex, thus improve the endurance quality of forward osmosis membrane and extend its service life, solve positive infiltration applications bottleneck problem.Adopt DOPA and/or dopamine to carry out chemical modification and modification to screen cloth, both maintained the supporting layer structure of the original excellence of screen cloth, screen cloth hydrophily and reactive thus improve matching between screen cloth and cortex can be strengthened again.In addition, add in polyamine aqueous phase solution containing amino long-chain/hyperbranched macromolecular and surfactant, active group quantity can be improved, spatial configuration of molecules can be expanded again, be conducive to aqueous phase solution to sprawl at the complete of screen surface, thus improve the object of cortex integrality and adjustment cortex cross-linked structure. |
