Abstract
Novel hybrid inorganic/organic polyphosphazene nanofibers were synthesized in situ polymerization, and the waterborne
polyurethane composites based on it were pre pared. The structure of nanofibers is investigated by Fourier trans
form infrared spectroscopy. The microstructure of the composites is investigated by scanning electron microscope which
indicated that the nanofibers were uniformly dispersed and showed go od adhesion with matrix. In comparison with it, the Tg
and thermal stability of the composites are all increased. Also, the tensile strength and elongation at break of the composit es
are all improved. The hydrophobic performance of the composites has a sig nificant difference with the filling content
increased by investigation on the surface..
