Description 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. (C) 2020 Published by Elsevier Ltd.
