| titleOfInvention | Method for modifying active layer of aromatic polyamide composite membrane and application thereof |
| abstract | The invention provides a modification method of an aromatic polyamide composite membrane, which comprises the steps of preparing the aromatic polyamide composite membrane containing azide groups through nucleophilic substitution reaction, and then adopting Cu I Catalyzing click chemical reaction between alkyne and azide to prepare the aromatic polyamide composite membrane connected with polyethylene glycol monomethyl ether, and finally realizing modification of the aromatic polyamide composite membrane. The anti-pollution performance test of the modified aromatic polyamide composite membrane disclosed by the invention shows that the anti-pollution performance of the membrane is improved after modification, the service life of the modified membrane is prolonged, the modification effect is durable, the performance of the polyethylene glycol monoethyl ether on the surface can be fully exerted, the polyethylene glycol monoethyl ether is not easy to run off, the anti-pollution capacity and the hydrophilicity of the membrane are improved, the efficiency in sewage treatment is higher, the hydrophilicity of the membrane cannot be reduced after the membrane is used for many times, and the commercial application value is wide. |
