Synthesis of Polymeric Schiff Base (PSB) Nanostructural Materials via Interfacial Polymerization

摘要

Nanostructural materials of polymeric Schiff base (PSB) have been selectively synthesized via interfacial polymerization (IP) by modifying the polymerization process. The effects of synthesizing methods, catalyst, the monomer concentration and the reaction time on the morphology of PSB nanostructural materials are investigated. The samples are characterized by TEM, FT-IR, UV-Vis, XRD, thermal analysis, and electrical conductivity measurement techniques. The results show that the PSB nanostructural materials, such as nano-films and -rods, can be obtained via IP. Na~+ and NH_4~+ ions act as shape-regulated agents. Na~+ ion can control the growth of PSB nuclei along two-dimension to obtain PSB nanofilms and NH_4~+ is advantage to the growth of PSB nuclei along one-dimension to obtain PSB nanorods. It is also found that the polymer nanocrystals show high thermal stability and the iodine-doped polymer is a semiconductor material.
