| titleOfInvention | The method of the preparation method and its modified polyvinilidene fluoride microfiltration membranes of difunctional block polymer |
| abstract | The invention discloses a kind of difunctional block polymer that can be carried out sol-gel reaction and by the modified PVDF microfiltration membranes of the block polymer to improve its hydrophilic and antifouling property method.Specifically can by the following method and step realize: difunctional block polymer is obtained by Transfer Radical Polymerization；Prepared difunctional block polymer is completely dissolved, difunctional block polymer solution is obtained；Stirring, while a small amount of hydrochloric acid tetrahydrofuran solution and water being added into polymer solution, places into PVDF microfiltration membranes, impregnate 5 at 20~30 DEG C~for 24 hours；PVDF microfiltration membranes are taken out, are washed with water, are then dried in vacuo at 105 DEG C to get difunctional block polymer modified polyvinilidene fluoride microfiltration membranes are arrived.The shortcomings that the method disclosed in the present greatly improves the hydrophilicity and antifouling property of PVDF microfiltration membranes, overcomes existing pvdf membrane modification technology and deficiency. |
