One-Pot Synthesis of Poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol) Nanotubes via an In Situ Template Approach

摘要

PZS nanotubes have been prepared by poly-condensation of HCCP and BPS in the presence of TEA. In the one-pot synthesis, the TEACl nanocrystals produced in situ during the polymerization act as templates for the PZS nanotubes. The TEACl nanocrystals were completely removed by washing with water. It was found that the diameters and lengths of the nanotubes can be controlled by adjusting the synthetic parameters. The PZS nanotubes have been well characterized by means of FTIR, NMR, SEM, TEM, EDX, and XRD studies. This approach could be extended to other similar polymerizations and used to obtain polymer nanotubes with controlled dimensions.
