Project at a Glance Contents on the CD ROM
  • Polyphosphazenes are a class of inorganic polymers with the repeat unit (-RR'P=N-). The substituents R,R' are usually alkoxy, amino, (R2N), or halogens (such as chloride or fluoride).
  • Polyphosphazenes are typically prepared by the thermal ring-opening polymerization of hexachlorophosphazene (Cl2PN)3 followed by esterification of the intermediate poly(dichlorophosphazene) with either amines or sodium salts of alcohols.
  • Most polyphosphazenes are colorless and exhibit high thermal stability, although they are somewhat sensitive to base hydrolysis.
  • Polyphosphazenes containing polyether side chains are good ionic conductors for lithium triflate. They are among the few polymers that will dissolve such salts.
  • Polyphosphazene is currently the highest performing membrane material for Methanol based Proton-Exchange Membrane (PEM) Fuel Cells. This fuel cell type is ideal for miniature power supply and is a leading candidate for automotive applications.
  • Medical applications include: Drug Delivery, Biological Membranes, Coatings, and polymeric medical devices and components such as prosthetics and implants.
  • Polyphosphazenes are used as flame retardants, additives, performance polymers, and in specialty applications.
  • Polyphosphazenes are being used to make membranes more thermally, mechanically, and chemically stable, as well as to enhance selectivity and overall performance. They are mainly used in electrodialysis, microfiltration, ultrafiltration, and reverse osmosis applications.
  • These are hybrid organic-inorganic polymers that have a backbone comprised of phosphorus and nitrogen atoms with althernating double and single bonds.
  • Polyphosphazene based electrolytes containing different iodide salts were studied as components of dye-sensitized solar cell.
  • Polyphosphazenes bearing cationic moieties were synthesized from poly(dichloro)phosphazene, which in turn was obtained by thermal polymerization of hexachlorocyclotriphosphazene in 1,2,4-trichlorobenzene.
  • Linear polyphosphazene polymers by direct synthesis under anhydrous conditions from NH4Cl and at least one chlorphosporous compound selected from the group consisting of XPCl4 or X2POI3 where X is one or more substitutents.
