| titleOfInvention | Polyamide composite membrane and its preparation method and application |
| abstract | The present invention provides a polyamide composite membrane and a preparation method and application thereof. The surface roughness of the polyamide composite membrane of the present invention is obviously lower than that of the traditional polyamide composite membrane, which reduces the degree of the membrane being easily polluted, and improves the salt separation capability and service life of the membrane. The preparation method of the polyamide composite membrane of the present invention solves the problem of large surface roughness of the membrane caused by the traditional preparation method through the dynamic reaction of the diamine solution and the trimesoyl chloride solution on the surface of the polymer support layer. The polyamide composite membrane of the invention can be applied to the fields of seawater desalination, lithium extraction from salt lakes, sewage treatment, food processing, membrane bioreactor, metallurgical separation process and the like. |
