New nano-composite metal-polymer materials: dielectric behaviour

The design, structure and dielectric properties of a new generation of metal-containing polymer systems produced by cryochemical solid-state synthesis were investigated. The synthesis consists of low-temperature co-condensation of metal and monomer vapours followed by low-temperature solid-state polymerisation of the co-condensate. By this method, one obtains nano-heterogeneous composites with high content of stable metal nanoparticles of various sizes trapped inside a polymer matrix. Synthesized materials show specific dielectric responses, which are discussed in relation to material structure and electron transfer between nanoparticles (C) 2002 Elsevier Science B.V.
