MOF material composite nanofiltration membrane, preparation method and application

The invention relates to an MOF material composite nanofiltration membrane, a preparation method and application, and belongs to the technical field of nanofiltration membrane preparation. The ZIF-8 intermediate layer is successfully synthesized through a simple method that PEG participates in post-heat treatment, the particle size of the ZIF-8 intermediate layer can be remarkably adjusted through the adding amount of PEG, solvent-resistant organic nanofiltration membranes are prepared on the ZIF-8 intermediate layers with different particle sizes, flux can be doubled or above through adding of the ZIF-8 intermediate layer, interception is improved, and therefore the solvent-resistant organic nanofiltration membranes can be prepared on the ZIF-8 intermediate layers with different particle sizes. And ZIF-8 with different particle sizes show different fluxes. In addition, the ZIF-8 film cross-linked by the TETA has the characteristic of good organic solvent resistance. 本发明涉及一种MOF材料复合的纳滤膜、制备方法与应用，属于纳滤膜制备技术领域。通过一
