Most synthetic polymers are created from organic chain but inorganic polymeric materials with similar properties can be also utilized. Phosphazenes are inorganic materials with a backbone of regularly alternating phosphorus and nitrogen atoms with two organic or organometallic substituents linked to each phosphorus atom. Phosphazenes occurred as monomers as well as polymers. Polyphosphazene derivatives have many advantages, such as flame retardancy, which could be introduced to mixtures of phosphazenes with commercial polymers, too.

 Our research focuses on synthesizing cyclic phosphazene derivatives with required properties via two different methods – nucleophilic substitution or condensation methods, with the aim to prepare additives to commercial polymers. Some mixtures are able to create nanofibres by electrospinning technology. These fibres have potential applications, e.g. as a flame retardant cover material, etc.
