polyphosphazenes_2

Polyphosphazenes are a class of inorganic-organic hybrid polymers with a backbone of alternating phosphorus and nitrogen atoms, whose properties can be tailored through various organic side-group substitutions. These materials are valued in aerospace, biomedical, and specialty elastomer applications for their thermal stability, flame resistance, and chemical inertness; they offer advantages over conventional organic polymers where thermal performance and low flammability are critical. The material family continues to be refined in research settings for emerging applications requiring combined mechanical performance and environmental durability.
