摘要

Two polyarylaminophosphazenes, poly[bis(phenylamino)phosphazene] (PBAP) and poly[bis(p-trifluoroethoxyphenylamino)phosphazene] (PBTAP), were successfully synthesized by ring-opening polymerizations and nucleophilic substitution reactions. Their chemical structures, thermal properties, and surface properties were investigated by NMR, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and water contact angles (WCA). The results indicate that the glass-transition temperature (T-g), thermal stability, and WCAs of PBAP and PBTAP presented obviously differences; this suggested that PBTAP possessed the lower T-g and higher contact angle than PBAP. This was attributed to the influence of trifluoroethoxy at the para position of aniline. TGA measurements indicated that PBAP possessed a higher thermal stability than PBTAP; this was attributed to the strong electron-withdrawing influence of the trifluoroethoxy.
