| titleOfInvention | A kind of preparation method of the hollow polytetrafluoroethylene (PTFE) composite nanometer filtering film of lotus positive electricity |
| abstract | The invention discloses a kind of preparation methods of the hollow polytetrafluoroethylene (PTFE) composite nanometer filtering film of lotus positive electricity.The step of this method, is as follows：Carboxyl chitosan aqueous solution is injected inside hydrophobic polytetrafluoroethylhollow hollow fiber membrane with syringe, obtains active basement membrane；Inside the active basement membrane of aqueous solution injection of hyperbranched polyethyleneimine, intermediate coat 1 is obtained；The inside that the solution of the organic solvent of acyl chloride monomer is injected to intermediate coat 1, obtains intermediate coat 2；Deionized water is injected to the inside of intermediate coat 2, drying in drying box is then placed in, obtains the hollow polytetrafluoroethylene (PTFE) composite nanometer filtering film of lotus positive electricity.For the present invention using the reactivity between carboxyl chitosan, hyperbranched polyethyleneimine and acyl chloride monomer, filming technology is simple.In addition, using the unique molecular structure of hyperbranched polyethyleneimine, the composite nanometer filtering film of preparation is in lotus positive electricity, has the advantages that rejection is high.It can be used for the fields such as water process. |
