英文摘要： Novel membrane materials with good thermal stability, resistance to solvent, acid and base is developed by preparing polynapthylimides and studying their properties. a series of bis(chloro)naphthylimide monomers are prepared by the reaction of chloronaphthyl anhydride and aromatic diamines. Poly ether naphthlymides are prepared by the condensation polymerization of the bis(chloro)naphthylimide monomer and bisphenol-A. Polynaphthylimides are prepared using Ni(0) catalyzed coupling polymerization of bis(chloro)naphthylimide monomers. The effect of structure on thermal, hydrolysis and solvent resistance of polyimide is investigated. Novel gas separation, ultrafiltration and nanofiltration membranes are prepared and the relationship between the structure and membrane performance are studied. This project will build up the synthetic method and fabrication conditions for gas separation and nanofiltration membrane. The effect of the structure of chemical and membrane on membrane properties will be figure out. Novel high performance polynaphthylimide membrane will be obtained.
