In this work, we report the synthesis and characteristics of cyclomatrix polyphosphazene membranes based on interfacial polymerization between 1,1-tris(4-hydroxyphenyl)ethane hexachlorocyclotriphosphazene top alumina or polyacrylonitrile supports. The potential alumina-supported thin film composite as organic solvent nanofiltration has been confirmed with a polystyrene-based molecular weight cu...
