The controlled preparation of cross-linked polyphosphazene nanotubes of high stability via a sacrificial template route

We report on the controlled preparation of cross-linked poly(cyclotriphosphazene-co-4,4'-sulfonyldiphenol) (PZS) nanotubes using Ag nanowires as sacrificial templates. The as-prepared PZS nanotubes have a good chemical stability in concentrated nitric acid and an initial 475 degrees C thermal decomposition temperature in air.
