Synthesis and application of additives based on trifluoroethoxy-cyclo-phosphazene into polymer nanofibers

This paper is focused on the synthesis and application of phosphazene derivatives, hexakis(2,2,2–trifluoroethoxy)-cyclo-triphosphazene and tetrakis(2,2,2-trifluoroethoxy)-diamino-cyclo-triphosphazene. These compounds were used as additives into some common polymers. As the synthesized compounds themselves show enhanced hydrophobicity, the nanofibers, made from them by electrospinning technology, should exhibit the enhanced hydrophobicity, too. It was found that hydrophobic properties of fibers are influenced by number of trifluoroethoxy groups bound to the phosphazene cycle. The use of these modified nanofibers especially in surface protection is expected. The result of the use can be the creation of efficient, removable, compact protect layer for long-term objects storing.

Novel polyelectrolytes were synthesized by quaternization of the backbone of poly(alkoxy- and aryloxyphosphazenes) with strong alkylation reagents. As models for the synthesis of these polymers, similar quaternization reactions were also carried out on small-molecule alkoxy and aryloxy cyclotriphosphazenes. The quaternized small molecules and high polymers were characterized by 1H NMR, 31P NMR, DSC, TGA, and AC impedance studies. The quaternized poly(alkoxyphosphazenes) showed ionic conductivities of 2.58 × 10-4 S?cm-1 at 25 °C and 2.09 × 10 -3 S?cm-1 at 80 °C, which are among the highest values for known solvent-free ionically conducting polymers.
