In this
article, highly cross-linked inorganic and organic hybrid polyphosphazene
microspheres including amino groups on the surface have been successfully
obtained via self-assembly polycondensation approach using 4,4ʹ-diaminodiphenylmethane
and octachlorocyclotetraphosphazene which is a new crosslinker. Experiments
were performed without adding a surfactant or stabilizer, using only an
ultrasonic bath. Otherwise, effect of different molar ratios of the reactants,
reaction time and ultrasonic power were investigated on preparing
morphologically good spheres. The reactivity of octachlorocyclotetraphosphazene
was investigated comparing with hexachlorocyclotriphosphazene which is the most
popular crosslinker cyclic phosphazene molecule. The size of acquired microspheres
were approximately same, and 1.00μm. The novel microspheres were characterized
by SEM, FTIR, ZETA, UV, Fluorescense, XRD and TGA.
