Effect of low-dose irradiation on the surface properties of poly[(trifluoroethoxy)(telomer fluoro alkoxy)phosphazene]

The effect of low-dose ultraviolet and 3, irradiation on the surface and bulk properties of poly[(trifluoroethoxy)(telomer fluoro alkoxy)phosphazene], was found to initially result in an increased side chain mobility followed by a decreased mobility. The initial increase is attributed to partial cleavage of selected side chains followed by a decreased mobility as a result of interside chain crosslinking. These above effects and the solid state characterization of the polymers were documented by dynamic mechanical analysis, difference dielectric spectroscopy, electron microscopy, electron spectroscopy for chemical analysis, attenuated total internal reflection spectroscopy, contact angle measurements, differential scanning calorimetry, gel permeation chromatography, tensile stress strain, and mass spectroscopy. © 1984.
