Polyphosphazenes as an example of the element-blocks approach to new materials

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Polyphosphazenes are inorganic-organic high polymers with a backbone of alternating phosphorus and nitrogen atoms and two organic or organometallic side groups attached to each phosphorus. Most of these polymers are synthesized by macromolecular substitution reactions carried out on poly(dichlorophosphazene), (NPCl2)n. The chlorine substitution reactions involve alkoxides, aryloxides, primary or secondary amines, or a range of organometallic reagents. Structural variations are accomplished via the use of one, two, or more different nucleophiles and substituents along the polymer chain and by the employment of reagent size and reactivity to control polymer properties and emphasize specific uses. Applications have been developed for these polymers as elastomers, thermoplastics, biostable or bioerodible medical materials, fire-resistant lithium battery electrolytes, films, or foams, and gas and liquid separation membranes.
