Separations using polyphsphazene membranes

Reported in this paper are the separation characteristics and transport mechanisms of membranes formed from poly[bis(phenoxy)phosphazene] based polymers. Separations of industrial interest include water purification, gas separations, liquid state organic-water and organic-organic separations. Many of these environments are chemically aggressive which often leads to the failure of many standard organic-based membrane materials and the polyphosphazenes have been observed to effectively operate in such environments. In this paper, we will develop an argument that shows the value of custom tailoring these membrane materials to fit the specific application of water purification.
