| titleOfInvention | Preparation method of fluorinated organic nanoparticle-containing polyamide solvent-resistant nanofiltration membrane |
| abstract | The invention discloses a preparation method of a fluoride-containing organic nanoparticle polyamide solvent-resistant nanofiltration membrane, which takes polyamine, dopamine and fluoroalkyl mercaptan compounds as reactive monomers, forms fluoride organic nanoparticles through Michael addition and Schiff base reaction, and then forms a polyamide membrane containing fluoride organic nanoparticles on the surface of a porous support membrane through interfacial polymerization reaction with polyacyl chloride. The low surface energy characteristic of fluorinated organic nanoparticles is utilized to regulate and control the interfacial polymerization process, the chemical composition, microstructure and hydrophilicity and hydrophobicity of a polyamide separation layer are optimized, the polyamide solvent-resistant nanofiltration membrane with a unique pore channel structure is obtained, the prepared membrane has high separation selectivity and solvent permeation flux, and the membrane preparation method is simple and convenient, is easy to regulate and control, and has good industrial application prospects. |
