| titleOfInvention | A kind of hydrophobic type polymeric membrane composite coated hydrophilic modification method |
| abstract | The invention discloses a kind of hydrophobic type polymeric membrane composite coated hydrophilic modification methods, this method is specific as follows: preparing certain density tanning solution first, then the alcoholic solution of a certain amount of silane coupling agent is added thereto and stirs evenly, adjustment mixed solution pH to alkalinity；Then polymeric membrane is sequentially placed into isopropanol, deionized water, impregnated in tannin-silane coupler solution；After the completion of to be modified, by film taking-up with deionized water rinse multipass and in deionized water or drying at room temperature preservation to get hydrophilic modifying macromolecule membrane sample.The method of the present invention greatly improves the hydrophily and stability of hydrophobic type polymeric membrane, while modified technique is simple, low in cost, is with a wide range of applications. |
