MODIFIED POLYMERIC NANOFIBRES

Popis výsledku v původním jazyce

Most widely used commercial polymeric structures are designed from organic carbon backbones. Their properties can be modified using a wide range of both organic and inorganic additives, such as phosphazene derivatives. Phosphazene derivatives, containing the backbone of alternating phosphorus and nitrogen atoms with two organic, organometallic or inorganic side groups linked to each phosphorus atom, display a number of beneficial properties (e.g. hydrophobicity or flame retardancy), which may be transferred to the mixtures with polymers. The research focuses on synthesizing fully substituted cyclophosphazene derivatives containing, for instance, the NH2-, PhO-, C6H4(CF3)O-, Ph-, Me- and CF3CH2O- side groups. The suitable synthetized materials are later used as additives in some commercial polymers. From the resulting polymer mixtures the nanofibres were created using electrospinning technology. In the contrast to nanofibre layers made from pure commercial polymers, the modified nanofibre layers exhibit some different properties, especially hydrophobicity. These nanofibres were later tested in order to gauge their potential for practical application.
