Novel poly[cyclotriphosphazene‐ co ‐(4,4′‐sulfonyldiphenol)] nanofiber matrices were synthesized via a facile one‐pot polymerization. The fibers are 20–50 nm in diameter and 500 nm or more in length. Uniform nanoscale fibers linked covalently with each other and formed three‐dimensional matrices. The highly cross‐linked chemical structure of the nanofiber matrices was measured by means of Fourier transform infrared and quantitative solid‐state NMR spectroscopy. Experiments show the pH had an effect on the hydrolytic degradation of the polymer. The hydrolysis of the matrices could be accelerated by alkaline conditions. The as‐synthesized nanofiber matrices have potential applications in tissue engineering materials. Copyright © 2006 Society of Chemical Industry
