Organometallic derivatives of polyphosphazenes as precursors for metallic nanostructured materials (SPRINGER, 2006-12)Co-polyphosphazenes containing anchored organometallic fragments are useful precursors for nanostructured metallic materials. Pyrolysis in air at 800 degrees yields metallic nanoparticles of the type, M degrees/M (x) O (y) ...
